Changeset 2799 for code/branches/gui/src/core/Core.cc

Timestamp:

Mar 18, 2009, 9:15:39 PM (15 years ago)

Author:

rgrieder

Message:

Moved all core related initialisations from Main.cc and GSRoot.cc to Core.cc so that everything sticks together more obviously.

Renamed —directory command line argument: Name really doesn't say what it is.
using —writingPathSuffix now. Not much better, but at least you wonder
