# 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)

# 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 :)
