Running More Than One Sup At A Time

Ferret doesn't allow concurrent access to the same index. As of 0.2, Sup locks the index explicitly to prevent this. Thus, the only way to run more than one Sup at a time is if they're pointed at two different, independent indexes. This is probably not useful in practice, but can be very useful for development purposes, as it allows you to avoid running run untested code against your actual mail index. Sup checks the environment variable SUP_BASE to determine the location of the sup directory. If that's not specified, it uses "~/.sup/". So in bash you can do something like "export SUP_BASE=/tmp/sup-test; ruby -I lib bin/sup-add <some source>" to start up sup, create the new sup directory and all requisite files automatically, and add the source. Then sup-sync and sup as normal.

If you are developing on debian, be aware of bug http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=542491 which breaks your search path (remove the unshift line from chronic.rb to fix that).
