Changeset 177 for cleverbox/trunk/cleverbox

Timestamp:

08/13/07 17:26:50 (5 years ago)

Author:

Message:

cleverbox :

• Factored environment in it's own class.
• Made environment initialisation atomic
• Created stubs for unit tests
• Created stubs for color in cli output
• It's now possible to use *nix user and group names instead of uid and gid in cleverbox.ini

Work in progress, probably buggy.
