identified in the URL (it's the first part of the URL path). The
instance home is the directory that was identified when you did
"roundup-admin init". You may specify any number of these name=home

# Revision 1.17 2001/10/29 23:55:44 richard
# Fix to CGI top-level index (thanks Juergen Hermann)
#
# Revision 1.16 2001/10/27 00:12:21 richard
# Fixed roundup-server for windows, thanks Juergen Hermann.
#
# Revision 1.15 2001/10/12 02:23:26 richard
# Didn't clean up after myself :)
#
# Revision 1.14 2001/10/12 02:20:32 richard
# server now handles setuid'ing much better
#
# 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 2001/09/29 13:27:00 richard
# CGI interfaces now spit up a top-level index of all the instances they can
# serve.
#
# Revision 1.11 2001/08/07 00:24:42 richard
# stupid typo
#
# Revision 1.10 2001/08/07 00:15:51 richard
# Added the copyright/license notice to (nearly) all files at request of
# Bizar Software.
#
# Revision 1.9 2001/08/05 07:44:36 richard
# Instances are now opened by a special function that generates a unique
# module name for the instances on import time.
#
# Revision 1.8 2001/08/03 01:28:33 richard
# Used the much nicer load_package, pointed out by Steve Majewski.
#
# Revision 1.7 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 1.6 2001/07/29 07:01:39 richard
# Added vim command to all source so that we don't get no steenkin' tabs :)
#
# Revision 1.5 2001/07/24 01:07:59 richard
# Added command-line arg handling to roundup-server so it's more useful
# out-of-the-box.
#
# Revision 1.4 2001/07/23 10:31:45 richard
# disabled the reloading until it can be done properly
#
# Revision 1.3 2001/07/23 08:53:44 richard
# Fixed the ROUNDUPS decl in roundup-server
# Move the installation notes to INSTALL
#
# Revision 1.2 2001/07/23 04:05:05 anthonybaxter
# actually quit if python version wrong
#
# Revision 1.1 2001/07/23 03:46:48 richard
# moving the bin files to facilitate out-of-the-boxness
#
# Revision 1.1 2001/07/22 11:15:45 richard
# More Grande Splite stuff
#
#
# vim: set filetype=python ts=4 sw=4 et si
