gnucash/libgnucash/backend/xml/gnc-xml-helper.cpp
Geert Janssens 83d14e1c1c Restructure the src directory
It is split into
- /libgnucash (for the non-gui bits)
- /gnucash (for the gui)
- /common (misc source files used by both)
- /bindings (currently only holds python bindings)

This is the first step in restructuring the code. It will need much
more fine tuning later on.
