All entries in the ChangeLog must be in the following format:

* YYYY-MM-DD - <email-address of user>

 - <description>

If more than one change has been performed, multiple <description>-lines can be used (with a new leading ' - ').
If the change is related to a bug, the description line has to comply to the following format:

 - Bugfix #<bug-no.>: <description what was changed, NOT the bug description>

If the change is related to a user story, the description must be in the following format:

 - US<number>: <description of what was changed/implemented>

Currently there exist 3 ChangeLogs, and an additional combined ChangedLog:

com.openexchange.usm      : changes performed on common/global USM packages/functions
com.openexchange.usm.eas  : changes specific to the EAS subsystem
com.openexchange.usm.json : changes specific to the JSON subsystem
USMPackaging              : combined changes of all 3 ChangeLogs

Any change performed must be logged in at least 1 of the specific ChangeLogs
(e.g. if only some code in the EAS-Sync-command was changed, only in EAS, if
a change in the JSON-MoveItems command was performed which required a change
to the Session-API, both in USM and JSON an entry must be made). In addition,
the same entry must be made in the combined ChangeLog.
