-5. Debugging scripts					*debug-scripts*
+5. Using Vim packages					*packages*
+
+A Vim package is a directory that contains one or more plugins.  The
+advantages over normal plugins:
+- A package can be downloaded as an archive and unpacked in its own directory.
+  Thus the files are not mixed with files of other plugins.  That makes it
+  easy to update and remove.
+- A package can be a git, mercurial, etc. repository.  That makes it really
+  easy to update.
+- A package can contain multiple plugins that depend on each other.
+- A package can contain plugins that are automatically loaded on startup and
+  ones that are only loaded when needed with `:packadd`.
+
+
+Using a package and loading automatically ~
+
+Let's assume your Vim files are in the "~/.local/share/nvim/site" directory
+and you want to add a package from a zip archive "/tmp/foopack.zip":
+	% mkdir -p ~/.local/share/nvim/site/pack/foo
+	% cd ~/.local/share/nvim/site/pack/foo
+	% unzip /tmp/foopack.zip
+
+The directory name "foo" is arbitrary, you can pick anything you like.
+
+You would now have these files under ~/.local/share/nvim/site:
+	pack/foo/README.txt
+	pack/foo/start/foobar/plugin/foo.vim
+	pack/foo/start/foobar/syntax/some.vim
+	pack/foo/opt/foodebug/plugin/debugger.vim
+
+When Vim starts up, after processing your .vimrc, it scans all directories in
+'packpath' for plugins under the "pack/*/start" directory.  First all those
+directories are added to 'runtimepath'.  Then all the plugins are loaded.
+See |packload-two-steps| for how these two steps can be useful.
+
+In the example Vim will find "pack/foo/start/foobar/plugin/foo.vim" and adds 
+"~/.local/share/nvim/site/pack/foo/start/foobar" to 'runtimepath'.
+
+If the "foobar" plugin kicks in and sets the 'filetype' to "some", Vim will
+find the syntax/some.vim file, because its directory is in 'runtimepath'.
+
+Vim will also load ftdetect files, if there are any.
+
+Note that the files under "pack/foo/opt" are not loaded automatically, only the
+ones under "pack/foo/start".  See |pack-add| below for how the "opt" directory
+is used.
+
+Loading packages automatically will not happen if loading plugins is disabled,
+see |load-plugins|.
+
+To load packages earlier, so that 'runtimepath' gets updated: >
+	:packloadall
+This also works when loading plugins is disabled.  The automatic loading will
+only happen once.
+
+
+Using a single plugin and loading it automatically ~
+
+If you don't have a package but a single plugin, you need to create the extra
+directory level:
+	% mkdir -p ~/.local/share/nvim/site/pack/foo/start/foobar
+	% cd ~/.local/share/nvim/site/pack/foo/start/foobar
+	% unzip /tmp/someplugin.zip
+
+You would now have these files:
+	pack/foo/start/foobar/plugin/foo.vim
+	pack/foo/start/foobar/syntax/some.vim
+
+From here it works like above.
+
+
+Optional plugins ~
+							*pack-add*
+To load an optional plugin from a pack use the `:packadd` command: >
+	:packadd foodebug
+This searches for "pack/*/opt/foodebug" in 'packpath' and will find
+~/.local/share/nvim/site/pack/foo/opt/foodebug/plugin/debugger.vim and source
+it.
+
+This could be done if some conditions are met.  For example, depending on
+whether Vim supports a feature or a dependency is missing.
+
+You can also load an optional plugin at startup, by putting this command in
+your |.vimrc|: >
+	:packadd! foodebug
+The extra "!" is so that the plugin isn't loaded with Vim was started with
+|--noplugin|.
+
+It is perfectly normal for a package to only have files in the "opt"
+directory.  You then need to load each plugin when you want to use it.
+
+
+Where to put what ~
+
+Since color schemes, loaded with `:colorscheme`, are found below
+"pack/*/start" and "pack/*/opt", you could put them anywhere.  We recommend
+you put them below "pack/*/opt", for example
+".vim/pack/mycolors/opt/dark/colors/very_dark.vim".
+
+Filetype plugins should go under "pack/*/start", so that they are always
+found.  Unless you have more than one plugin for a file type and want to
+select which one to load with `:packadd`.  E.g. depending on the compiler
+version: >
+	if foo_compiler_version > 34
+	  packadd foo_new
+	else
+	  packadd foo_old
+	endif
+
+The "after" directory is most likely not useful in a package.  It's not
+disallowed though.
+
+==============================================================================
+6. Creating Vim packages				*package-create*
+
+This assumes you write one or more plugins that you distribute as a package.
+
+If you have two unrelated plugins you would use two packages, so that Vim
+users can chose what they include or not.  Or you can decide to use one
+package with optional plugins, and tell the user to add the ones he wants with
+`:packadd`.
+
+Decide how you want to distribute the package.  You can create an archive or
+you could use a repository.  An archive can be used by more users, but is a
+bit harder to update to a new version.  A repository can usually be kept
+up-to-date easily, but it requires a program like "git" to be available.
+You can do both, github can automatically create an archive for a release.
+
+Your directory layout would be like this:
+   start/foobar/plugin/foo.vim    	" always loaded, defines commands
+   start/foobar/plugin/bar.vim    	" always loaded, defines commands
+   start/foobar/autoload/foo.vim  	" loaded when foo command used
+   start/foobar/doc/foo.txt       	" help for foo.vim
+   start/foobar/doc/tags          	" help tags
+   opt/fooextra/plugin/extra.vim  	" optional plugin, defines commands
+   opt/fooextra/autoload/extra.vim  	" loaded when extra command used
+   opt/fooextra/doc/extra.txt  	        " help for extra.vim
+   opt/fooextra/doc/tags  	        " help tags
+
+This allows for the user to do: >
+	mkdir ~/.local/share/nvim/site/pack/myfoobar
+	cd ~/.local/share/nvim/site/pack/myfoobar
+	git clone https://github.com/you/foobar.git
+
+Here "myfoobar" is a name that the user can choose, the only condition is that
+it differs from other packages.
+
+In your documentation you explain what the plugins do, and tell the user how
+to load the optional plugin: >
+	:packadd! fooextra
+
+You could add this packadd command in one of your plugins, to be executed when
+the optional plugin is needed.
+
+Run the `:helptags` command to generate the doc/tags file.  Including this
+generated file in the package means that the user can drop the package in his
+pack directory and the help command works right away.  Don't forget to re-run
+the command after changing the plugin help: >
+	:helptags path/start/foobar/doc
+	:helptags path/opt/fooextra/doc
+
+
+Dependencies between plugins ~
+							*packload-two-steps*
+Suppose you have a two plugins that depend on the same functionality. You can
+put the common functionality in an autoload directory, so that it will be
+found automatically.  Your package would have these files:
+
+	pack/foo/start/one/plugin/one.vim  >
+		call foolib#getit()
+<	pack/foo/start/two/plugin/two.vim >
+		call foolib#getit()
+<	pack/foo/start/lib/autoload/foolib.vim >
+		func foolib#getit()
+
+This works, because loading packages will first add all found directories to
+'runtimepath' before sourcing the plugins.

+
+A package is a set of files that you can add to Vim.  There are two kinds of
+packages: optional and automatically loaded on startup.
+
+The Vim distribution comes with a few packages that you can optionally use.
+For example, the vimball plugin.  This plugin supports creating and using
+vimballs (self-installing Vim plugin archives).
+
+To start using the vimball plugin, add one line to your vimrc file: >
+	packadd vimball
+
+That's all!  You can also type the command to try it out.  Now you can find
+help about this plugin: >
+	:help vimball
+
+This works, because when `:packadd` loaded the plugin it also added the
+package directory in 'runtimepath', so that the help file can be found.  The
+tags for vimball's help are already created.  If you need to generate the help
+tags for a package, see the `:helptags` command.
+
+You can find packages on the Internet in various places.  It usually comes as
+an archive or as a repository.  For an archive you can follow these steps:
+	1. create the package directory: >
+		mkdir -p ~/.local/share/nvim/site/pack/fancy
+<	   "fancy" can be any name of your liking.  Use one that describes the
+	   package.
+	2. unpack the archive in that directory.  This assumes the top
+	   directory in the archive is "start": >
+	   	cd ~/.local/share/nvim/site/pack/fancy
+		unzip /tmp/fancy.zip
+<	   If the archive layout is different make sure that you end up with a
+	   path like this:
+		~/.local/share/nvim/site/pack/fancy/start/fancytext/plugin/fancy.vim ~
