Sophie 2.0 consists of three editions(plug-in sets):
 * org.sophie2.author
 * org.sophie2.reader
 * org.sophie2.server

Each edition is runnable through:
 * Eclipse, using some fake classes that simulate plug-in behavior
 * Apache Felix OSGI implementation.

Every edition has the following structure:
 * / - main application catalog
  * /modules/  - containes plug-ins(in the form of jar-files or unpacked jar-files) that are/can be used in this edition
  * /conf/ - contains plug-ins configuration files and global configuration files
  * /log/ - contains application log(s)
  * /data/ - contains mutable resources(i.e book templates).
  * run-files

At this time each edition has its own module. It is responsible for loading the correct set of plug-ins.

 * Currently there is still no Reader edition amd the structure is not as described. Should be fixed in the next revision. --boyan@2008-22-12
