56# Description:
57# ------------
58# This tool moves text from "Current Revisions:" to "Former Revisions:" and
59# adds the svn timestamp. It works with the folders SOURCE and SCRIPTS
60#
61# Usage:
62# a) go to the source directory (e.g. current_version/trunk and perform:
63#    "document_changes",
64# b) or call "document_changes" directly and add the path to the source code as
65#    argument
66#    (e.g. document_changes trunk)
67#
68# Note:
69# The script will only work properly if the two following conditions are met:
70# 1) the 2nd line after "Current Revisions:" must contain text,
71# 2) the last line before "Former Revisions:" must not contain text.
