# This script turns a directory full of revision files back into
# a single XML file suitable for sorting and then fast-loading.
#
# It modifies the title in the XML to match the file name.
# Therefore, you can move or rename the files, and the resulting
# XML will me modified to reflect the changes in the filesystem.
# (this is kind of too bad...  otherwise we could just concatenate
# the revision files and ignore rexml completely).
