ninjahelper: moved (and enhanced) vservers-related functions to lib/vservers. dup.helper, pgsql.helper: use these functions
rdiff ninjahelper bugfixes:
used to expand '*' in default source directories
the "Cancel" buttons used to have a weird behaviour... at least
- code refactor: moved to lib/ some code that has to be shared between
+ code refactor:
+ moved to lib/ some code that has to be shared between
backupninja and ninjahelper
added duplicity ninjahelper
+ a bunch of Vserver-related functions for ninjahelper in lib/vservers.in
version 0.9.1 -- November 05 2005
rearranged source so that it is relocatable with autotools
