# $Log: not supported by cvs2svn $
# Revision 1.14  2001/10/27 00:22:35  richard
# Fixed some URL issues in roundup.cgi, again thanks Juergen Hermann.
#
# Revision 1.13  2001/10/05 02:23:24  richard
#  . roundup-admin create now prompts for property info if none is supplied
#    on the command-line.
#  . hyperdb Class getprops() method may now return only the mutable
#    properties.
#  . Login now uses cookies, which makes it a whole lot more flexible. We can
#    now support anonymous user access (read-only, unless there's an
#    "anonymous" user, in which case write access is permitted). Login
#    handling has been moved into cgi_client.Client.main()
#  . The "extended" schema is now the default in roundup init.
#  . The schemas have had their page headings modified to cope with the new
#    login handling. Existing installations should copy the interfaces.py
#    file from the roundup lib directory to their instance home.
#  . Incorrectly had a Bizar Software copyright on the cgitb.py module from
#    Ping - has been removed.
#  . Fixed a whole bunch of places in the CGI interface where we should have
#    been returning Not Found instead of throwing an exception.
#  . Fixed a deviation from the spec: trying to modify the 'id' property of
#    an item now throws an exception.
#
# Revision 1.12  2001/10/01 05:55:41  richard
# Fixes to the top-level index
#
# Revision 1.11  2001/09/29 13:27:00  richard
# CGI interfaces now spit up a top-level index of all the instances they can
# serve.
#
# Revision 1.10  2001/08/07 00:24:42  richard
# stupid typo
#
# Revision 1.9  2001/08/07 00:15:51  richard
# Added the copyright/license notice to (nearly) all files at request of
# Bizar Software.
#
# Revision 1.8  2001/08/05 07:43:52  richard
# Instances are now opened by a special function that generates a unique
# module name for the instances on import time.
#
# Revision 1.7  2001/08/03 01:28:33  richard
# Used the much nicer load_package, pointed out by Steve Majewski.
#
# Revision 1.6  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 1.5  2001/07/29 07:01:39  richard
# Added vim command to all source so that we don't get no steenkin' tabs :)
#
# Revision 1.4  2001/07/23 04:47:27  anthonybaxter
# renamed ROUNDUPS to ROUNDUP_INSTANCE_HOMES
# sys.exit(0) if python version wrong.
#
# Revision 1.3  2001/07/23 04:33:30  richard
# brought the CGI instance config dict in line with roundup-server
#
# Revision 1.2  2001/07/23 04:31:40  richard
# Fixed the roundup CGI script for updates to cgi_client.py
#
# Revision 1.1  2001/07/22 11:47:07  richard
# More Grande Splite
#
