Revision: 1.2
Committed: Thu Dec 21 22:41:34 2006 UTC (17 years, 5 months ago) by root
Branch: MAIN
Changes since 1.1: +3 -2 lines
Log Message: 
- updated cf.pm to use a more generic and extendable syntax,
  now that it is clear that we will have multiple "attachable" objects.
  maybe bite the bullet in C++ and make attachable virtual?
- completely rework the syntax for attaching and attachments
- update all extensions
