# Revision 1.10  2001/08/03 01:28:33  richard
# Used the much nicer load_package, pointed out by Steve Majewski.
#
# Revision 1.9  2001/08/03 00:59:34  richard
# Instance import now imports the instance using imp.load_module so that
# we can have instance homes of "roundup" or other existing python package
# names.
#
# Revision 1.8  2001/07/29 07:01:39  richard
# Added vim command to all source so that we don't get no steenkin' tabs :)
#
# Revision 1.7  2001/07/28 07:59:53  richard
# Replaced errno integers with their module values.
# De-tabbed templatebuilder.py
#
# Revision 1.6  2001/07/24 11:18:25  anthonybaxter
# oops. left a print in
#
# Revision 1.5  2001/07/24 10:54:11  anthonybaxter
# oops. Html.
#
# Revision 1.4  2001/07/24 10:46:22  anthonybaxter
# Added templatebuilder module. two functions - one to pack up the html base,
# one to unpack it. Packed up the two standard templates into htmlbases.
# Modified __init__ to install them.
#
# __init__.py magic was needed for the rather high levels of wierd import magic.
# Reducing level of import magic == (good, future)
#
# Revision 1.3  2001/07/23 08:45:28  richard
# ok, so now "./roundup-admin init" will ask questions in an attempt to get a
# workable instance_home set up :)
# _and_ anydbm has had its first test :)
