+# @xen-orchestra/cron [![Build Status](https://travis-ci.org/vatesfr/xen-orchestra.png?branch=master)](https://travis-ci.org/vatesfr/xen-orchestra)
+
+> Focused, well maintained, cron parser/scheduler
+
+## Install
+
+Installation of the [npm package](https://npmjs.org/package/@xen-orchestra/cron):
+
+```
+> npm install --save @xen-orchestra/cron
+```
+
+### Pattern syntax
+
+```
+<minute> <hour> <day of month> <month> <day of week>
+```
+
+
+Each entry can be:
+
+- a single value
+- a range (`0-23` or `*/2`)
+- a list of values/ranges (`1,8-12`)
+
+A wildcard (`*`) can be used as a shortcut for the whole range
+(`first-last`).
+
+Step values can be used in conjunctions with ranges. For instance,
+`1-7/2` is the same as `1,3,5,7`.
+
+| Field            | Allowed values |
+|------------------|----------------|
+| minute           | 0-59           |
+| hour             | 0-23           |
+| day of the month | 1-31 or 3-letter names (`jan`, `feb`, …) |
+| month            | 0-11           |
+| day of week      | 0-7 (0 and 7 both mean Sunday) or 3-letter names (`mon`, `tue`, …) |
+
+> Note: the month range is 0-11 to be compatible with
+> [cron](https://github.com/kelektiv/node-cron), it does not appear to
+> be very standard though.
+
+### API
+
+`createSchedule(pattern: string, zone: string = 'utc'): Schedule`
+
+> Create a new schedule.
+
+- `pattern`: the pattern to use, see [the syntax](#pattern-syntax)
+- `zone`: the timezone to use, use `'local'` for the local timezone
+
+```js
+import { createSchedule } from '@xen-orchestra/cron'
+
+const schedule = createSchedule('0 0 * * sun', 'America/New_York')
+```
+
+`Schedule#createJob(fn: Function): Job`
+
+> Create a new job from this schedule.
+
+- `fn`: function to execute, if it returns a promise, it will be
+  awaited before scheduling the next run.
+
+```js
+const job = schedule.createJob(() => {
+  console.log(new Date())
+})
+```
+
+`Schedule#next(n: number): Array<Date>`
+
+> Returns the next dates matching this schedule.
+
+- `n`: number of dates to return
+
+```js
+schedule.next(2)
+// [ 2018-02-11T05:00:00.000Z, 2018-02-18T05:00:00.000Z ]
+```
+
+`Schedule#startJob(fn: Function): () => void`
+
+> Start a new job from this schedule and return a function to stop it.
+
+- `fn`: function to execute, if it returns a promise, it will be
+  awaited before scheduling the next run.
+
+```js
+const stopJob = schedule.startJob(() => {
+  console.log(new Date())
+})
+stopJob()
+```
+
+`Job#start(): void`
+
+> Start this job.
+
+```js
+job.start()
+```
+
+`Job#stop(): void`
+
+> Stop this job.
+
+```js
+job.stop()
+```
+
+## Development
+
+```
+# Install dependencies
+> yarn
+
+# Run the tests
+> yarn test
+
+# Continuously compile
+> yarn dev
+
+# Continuously run the tests
+> yarn dev-test
+
+# Build for production (automatically called by npm install)
+> yarn build
+```
+
+## Contributions
+
+Contributions are *very* welcomed, either on the documentation or on
+the code.
+
+You may:
+
+- report any [issue](https://github.com/vatesfr/xen-orchestra/issues)

+# xen-api [![Build Status](https://travis-ci.org/vatesfr/xen-orchestra.png?branch=master)](https://travis-ci.org/vatesfr/xen-orchestra)
+
+> Connector to the Xen API
+
+Tested with:
+
+- XenServer 7.3
+- XenServer 7.2
+- XenServer 7.1
+- XenServer 7
+- XenServer 6.5
+- XenServer 6.2
+- XenServer 5.6
+
+## Install
+
+Installation of the [npm package](https://npmjs.org/package/xen-api):
+
+```
+> npm install --save xen-api
+```
+
+## Usage
+
+### Library
+
+```javascript
+const { createClient } = require('xen-api')
+
+const xapi = createClient({
+  url: 'https://xen1.company.net',
+  allowUnauthorized: false,
+  auth: {
+    user: 'root',
+    password: 'important secret password'
+  },
+  readOnly: false
+})
+```
+
+Options:
+
+- `url`: address of a host in the pool we are trying to connect to
+- `allowUnauthorized`: whether to accept self-signed certificates
+- `auth`: credentials used to sign in (can also be specified in the URL)
+- `readOnly = false`: if true, no methods with side-effects can be called
+
+```js
+// Force connection.
+xapi.connect().catch(error => {
+  console.error(error)
+})
+
+// Watch objects.
+xapi.objects.on('add', objects => {
+  console.log('new objects:', objects)
+})
+```
+
+> Note: all objects are frozen and cannot be altered!
+
+Custom fields on objects (hidden − ie. non enumerable):
+- `$type`: the type of the object (`VM`, `task`, …);
+- `$ref`: the (opaque) reference of the object;
+- `$id`: the identifier of this object (its UUID if any, otherwise its reference);
+- `$pool`: the pool object this object belongs to.
+
+Furthermore, any field containing a reference (or references if an
+array) can be resolved by prepending the field name with a `$`:
+
+```javascript
+console.log(xapi.pool.$master.$resident_VMs[0].name_label)
+// vm1
+```
+
+### CLI
+
+A CLI is provided to help exploration and discovery of the XAPI.
+
+```
+> xen-api https://xen1.company.net root
+Password: ******
+root@xen1.company.net> xapi.status
+'connected'
+root@xen1.company.net> xapi.pool.master
+'OpaqueRef:ec7c5147-8aee-990f-c70b-0de916a8e993'
+root@xen1.company.net> xapi.pool.$master.name_label
+'xen1'
+```
+
+To ease searches, `find()` and `findAll()` functions are available:
+
+```
+root@xen1.company.net> findAll({ $type: 'vm' }).length
+183
+```
+
+## Development
+
+```
+# Install dependencies
+> npm install
+
+# Run the tests
+> npm test
+
+# Continuously compile
+> npm run dev
+
+# Continuously run the tests
+> npm run dev-test
+
+# Build for production (automatically called by npm install)
+> npm run build
+```
+
+## Contributions
+
+Contributions are *very* welcomed, either on the documentation or on
+the code.
+
+You may:
+
+- report any [issue](https://github.com/xen-api/issues)
+  you've encountered;
+- fork and create a pull request.

+  xo-cli --register [--expiresIn duration] <XO-Server URL> <username> [<password>]
+    Registers the XO instance to use.
+
+    --expiresIn duration
+      Can be used to change the validity duration of the
+      authorization token (default: one month).
+
+  xo-cli --unregister
+    Remove stored credentials.
+
+  xo-cli --list-commands [--json] [<pattern>]...
+    Returns the list of available commands on the current XO instance.
+
+    The patterns can be used to filter on command names.
+
+  xo-cli --list-objects [--<property>]… [<property>=<value>]...
+    Returns a list of XO objects.
+
+    --<property>
+      Restricts displayed properties to those listed.
+
+    <property>=<value>
+      Restricted displayed objects to those matching the patterns.
+
+  xo-cli <command> [<name>=<value>]...
+    Executes a command on the current XO instance.
+```
+
+#### Register your XO instance
+
+```
+> xo-cli --register http://xo.my-company.net admin@admin.net admin
+Successfully logged with admin@admin.net
+```
+
+Note: only a token will be saved in the configuration file.
+
+#### List available objects
+
+Prints all objects:
+
+```
+> xo-cli --list-objects
+```
+
+It is possible to filter on object properties, for instance to prints
+all VM templates:
+
+```
+> xo-cli --list-objects type=VM-template
+```
+
+#### List available commands
+
+```
+> xo-cli --list-commands
+```
+
+Commands can be filtered using patterns:
+
+```
+> xo-cli --list-commands '{user,group}.*'
+```
+
+#### Execute a command
+
+The same syntax is used for all commands: `xo-cli <command> <param
+name>=<value>...`
+
+E.g., adding a new server:
+
+```
+> xo-cli server.add host=my.server.net username=root password=secret-password
+42
+```
+
+The return value is the identifier of this new server in XO.
+
+Parameters (except `true` and `false` which are correctly parsed as
+booleans) are assumed to be strings, for other types, you may use JSON
+encoding by prefixing with `json:`:
+
+```
+> xo-cli foo.bar baz='json:[1, 2, 3]'
+```
+
+##### Configuration export
+
+```
+> xo-cli xo.exportConfig @=config.json
+```
+
+##### VM export
+
+```
+> xo-cli vm.export vm=a01667e0-8e29-49fc-a550-17be4226783c @=vm.xva
+```
+
+##### VM import
+
+ ```
+> xo-cli vm.import host=60a6939e-8b0a-4352-9954-5bde44bcdf7d @=vm.xva
+```
+
+## Development
+
+```
+# Install dependencies
+> yarn
+
+# Run the tests
+> yarn test
+
+# Continuously compile
+> yarn dev
+
+# Continuously run the tests
+> yarn dev-test
+
+# Build for production (automatically called by npm install)
+> yarn build
+```

+GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published
+    by the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <http://www.gnu.org/licenses/>.

+# xo-collection [![Build Status](https://travis-ci.org/vatesfr/xen-orchestra.png?branch=master)](https://travis-ci.org/vatesfr/xen-orchestra)
+
+> Generic in-memory collection with events
+
+## Install
+
+Installation of the [npm package](https://npmjs.org/package/xo-collection):
+
+```
+> npm install --save xo-collection
+```
+
+## Usage
+
+```javascript
+var Collection = require('xo-collection')
+```
+
+### Creation
+
+```javascript
+// Creates a new collection.
+var col = new Collection()
+```
+
+### Manipulation
+
+**Inserting a new item**
+
+```javascript
+col.add('foo', true)
+```
+
+- **Throws** `DuplicateItem` if the item is already in the collection.
+
+**Updating an existing item**
+
+```javascript
+col.update('foo', false)
+```
+
+- **Throws** `NoSuchItem` if the item is not in the collection.
+
+**Inserting or updating an item**
+
+```javascript
+col.set('bar', true)
+```
+
+**Notifying an external update**
+
+> If an item is an object, it can be updated directly without using
+> the `set`/`update` methods.
+>
+> To make sure the collection stays in sync and the correct events are
+> sent, the `touch` method can be used to notify the change.
+
+```javascript
+var baz = {}
+
+col.add('baz', baz)
+
+baz.prop = true
+col.touch('baz')
+```
+
+> Because this is a much used pattern, `touch` returns the item to
+> allow its direct modification.
+
+```javascript
+col.touch('baz').prop = false
+```
+
+- **Throws** `NoSuchItem` if the item is not in the collection.
+- **Throws** `IllegalTouch` if the item is not an object.
+
+**Removing an existing item**
+
+```javascript
+col.remove('bar')
+```
+
+- **Throws** `NoSuchItem` if the item is not in the collection.
+
+**Removing an item without error**
+
+This is the symmetric method of `set()`: it removes the item if it
+exists otherwise does nothing.
+
+```javascript
+col.unset('bar')
+```
+
+**Removing all items**
+
+```javascript
+col.clear()
+```
+
+### Query
+
+**Checking the existence of an item**
+
+```javascript
+var hasBar = col.has('bar')
+```
+
+**Getting an existing item**
+
+```javascript
+var foo = col.get('foo')
+
+// The second parameter can be used to specify a fallback in case the
+// item does not exist.
+var bar = col.get('bar', 6.28)
+```
+
+- **Throws** `NoSuchItem` if the item is not in the collection and no
+  fallback has been passed.
+
+**Getting a read-only view of the collection**
+
+> This property is useful for example to iterate over the collection
+> or to make advanced queries with the help of utility libraries such
+> as lodash.
+
+```javascript
+var _ = require('lodash')
+
+// Prints all the items.
+_.forEach(col.all, function (value, key) {
+  console.log('- %s: %j', key, value)
+})
+
+// Finds all the items which are objects and have a property
+// `active` which equals `true`.
+var results = _.where(col.all, { active: true })
+```
+
+**Getting the number of items**
+
+```javascript
+var size = col.size
+```
+
+### Events
+
+> The events are emitted asynchronously (at the next turn/tick of the
+> event loop) and are deduplicated which means, for instance, that an
+> addition followed by an update will result only in a single
+> addition.
+
+**New items**
+
+```javascript
+col.on('add', (added) => {
+  forEach(added, (value, key) => {
+    console.log('+ %s: %j', key, value)
+  })
+})
+```
+
+**Updated items**
+
+```javascript
+col.on('update', (updated) => {
+  forEach(updated, (value, key) => {
+    console.log('± %s: %j', key, value)
+  })
+})
+```
+
+**Removed items**
+
+```javascript
+col.on('remove', (removed) => {
+  // For consistency, `removed` is also a map but contrary to `added`
+  // and `updated`, the values associated to the keys are not
+  // significant since the items have already be removed.
+
+  forEach(removed, (value, key) => {
+    console.log('- %s', key)
+  })
+})
+```
+
+**End of update**
+
+> Emitted when all the update process is finished and all the update
+> events has been emitted.
+
+```javascript
+col.on('finish', () => {
+  console.log('the collection has been updated')
+})
+```
+
+### Iteration
+
+```javascript
+for (const [key, value] of col) {
+  console.log('- %s: %j', key, value)
+}
+
+for (const key of col.keys()) {
+  console.log('- %s', key)
+}
+
+for (const value of col.values()) {
+  console.log('- %j', value)
+}
+```
+
+### Views
+
+```javascript
+const View = require('xo-collection/view')
+```
+
+> A view is a read-only collection which contains only the items of a
+> parent collection which satisfy a predicate.
+>
+> It is updated at most once per turn of the event loop and therefore
+> can be briefly invalid.
+
+```javascript
+const myView = new View(parentCollection, function predicate (value, key) {
+  // This function should return a boolean indicating whether the
+  // current item should be in this view.
+})
+```
+
+## Development
+
+```
+# Install dependencies
+> npm install
+
+# Run the tests
+> npm test
+
+# Continuously compile
+> npm run dev
+
+# Continuously run the tests
+> npm run dev-test
+
+# Build for production (automatically called by npm install)
+> npm run build
+```
+

+
+Contributions are *very* welcomed, either on the documentation or on
+the code.
+
+You may:
+
+- report any [issue](https://github.com/vatesfr/xen-orchestra/issues)
+  you've encountered;

+# xo-lib [![Build Status](https://travis-ci.org/vatesfr/xen-orchestra.png?branch=master)](https://travis-ci.org/vatesfr/xen-orchestra)
+
+> Library to connect to XO-Server.
+
+## Install
+
+Installation of the [npm package](https://npmjs.org/package/xo-lib):
+
+```
+npm install --save xo-lib
+```
+
+Then require the package:
+
+```javascript
+import Xo from 'xo-lib'
+```
+
+## Usage
+
+> If the URL is not provided and the current environment is a web
+> browser, the location of the current page will be used.
+
+```javascript
+// Connect to XO.
+const xo = new Xo({ url: 'https://xo.company.tld' })
+
+// Let's start by opening the connection.
+await xo.open()
+
+// Must sign in before being able to call any methods (all calls will
+// be buffered until signed in).
+await xo.signIn({
+  email: 'admin@admin.net',
+  password: 'admin'
+})
+
+console('signed as', xo.user)
+```
+
+The credentials can also be passed directly to the constructor:
+
+```javascript
+const xo = Xo({
+  url: 'https://xo.company.tld',
+  credentials: {
+    email: 'admin@admin.net',
+    password: 'admin',
+  }
+})
+
+xo.open()
+
+xo.on('authenticated', () => {
+  console.log(xo.user)
+})
+```
+
+> If the URL is not provided and the current environment is a web
+> browser, the location of the current page will be used.
+
+### Connection
+
+```javascript
+await xo.open()
+
+console.log('connected')
+```
+
+### Disconnection
+
+```javascript
+xo.close()
+
+console.log('disconnected')
+```
+
+### Method call
+
+```javascript
+const token = await xo.call('token.create')
+
+console.log('Token created', token)
+```
+
+### Status
+
+The connection status is available through the status property which
+is *open*, *connecting* or *closed*.
+
+```javascript
+console.log('%s to xo-server', xo.status)
+```
+
+### Current user
+
+Information about the user account used to sign in is available
+through the `user` property.
+
+```javascript
+console.log('Current user is', xo.user)
+```
+
+> This property is null when the status is not connected.
+
+### Events
+
+```javascript
+xo.on('open', () => {
+  console.log('connected')
+})
+```
+
+```javascript
+xo.on('closed', () => {
+  console.log('disconnected')
+})
+```
+
+```javascript
+xo.on('notification', function (notif) {
+  console.log('notification:', notif.method, notif.params)
+})
+```
+
+```javascript
+xo.on('authenticated', () => {
+  console.log('authenticated as', xo.user)
+})
+
+xo.on('authenticationFailure', () => {
+  console.log('failed to authenticate')
+})
+```
+
+## Development
