Last change on this file since 538 was 538, checked in by bcornec, 18 years ago

Begining of modifications => DOS NOT WORK FOR NOW.
This is done to be merged in trunk. stable will later point back to current 2.0.8 content

Use of mindi conf file in mindi + /var/cache/mindi as a default place
Use of mondo conf file in mondo + separation of messages.
Ultimate goal is to have a cleaner design of files vs functions.
