Changeset 6630 for trunk/gli/src/org/greenstone/gatherer/Configuration.java

Timestamp:

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.
