Changeset 6630 for trunk/gli/src/org/greenstone

Timestamp:

2004-01-28T14:37:50+13:00 (20 years ago)

Author:

jmt12

Message:

File associations are now stored in the user specific config. Also, to make everyones life a little easier, the config has a version number which if no match is found, causes the current config to be backed-up, and a new default config created.

Location:

trunk/gli/src/org/greenstone/gatherer

Files:

• Configuration.java (modified) (3 diffs)
• file/FileAssociationManager.java (modified) (10 diffs)
