The widgets

The widgets
-----------
The widgets are described by the technical recommendations
[widgets] and [widgets-digsig].
### signature
The application framework
This is the original part of our work here
### directory where are stored applications
Applications can be installed in different places: the system itself, extension device.
On a phone application are typically installed on the sd card.
This translates to:
- /usr/applications: system wide applications
- /opt/applications: removable applications
From here those paths are referenced as: "APPDIR".
Organization of directory of applications
=========================================
The main path for applications is: APPDIR/PKGID/VER.
Where:
- APPDIR is as defined above
- PKGID is a directory whose name is the package identifier
- VER is the version of the package MAJOR.MINOR
This organization has the advantage to allow several versions to leave together.
This is needed for some good reasons (rolling back) and also for less good reasons (user habits).
Identity of installed files
---------------------------
All files are installed as user "userapp" and group "userapp".
All files have rw(x) for user and r-(x) for group and others.
This allows every user to read every file.
labeling the directories of applications
-----------------------------------------
organization of data
====================
The data of a user are in its directory and are labelled using the labels of the application
