New Revision: 6961

Modified:
   trunk/tools/download-redirector-v2/mirrordoctor/mirrordoctor.py
Log:
mb export:
- implement a new output format, named "vcs".
  This format generates a file tree which can be imported/committed into
  a version control system (VCS). This can be used to periodically dump
  the database into a working copy of such a repository and commit the
  changes, making use of the commit mail mechanism of the VCS to send
  change notifications.
  You need to specify --target-dir=PATH.
  If you use the --commit=VCS option, "VCS commit" will be run after the
  export on the directory.

-        Output format is suitable to be used in a Django ORM.
+        There are different output formats:
 
+        Format "django" is suitable to be used in a Django ORM.
+
+        Format "postgresql" is suitable to be imported into a PostgreSQL
+        database.
+
+        Format "vcs" generates a file tree which can be imported/committed into

+        change notifications.
+        You need to specify --target-dir=PATH for this. 
+        If you use the --commit=VCS option, "VCS commit" will be run after the
