# Tweak Subversion log messages
# -----------------------------
#
# It sure would be nice to be able to change the log messages on
# committed revisions of the Subversion repository via the web. This
# is a quick attempt at making that happen.
#
# The idea here is that you visit this script at the web page. With
# no action supplied, it will present a form asking for the revision
# of the log you wish to change.
#
# Upon submitting the form, it will come back with yet another form,
# which will:
#
# - Display the current log message as static text.
# - Present a textarea for editing, initialized with the current
# log message.
#
# The user can edit the message in the textarea, then submit that form,
# which will return a confirmation and show the new log message.
