29# Initial revision

31# Description:
32# ------------
33# This tool moves text from "Current Revisions:" to "Former Revisions:" and
34# adds the svn timestamp. It works with the folders SOURCE and SCRIPTS
35#
36# Usage:
37# a) go to the source directory (e.g. current_version/trunk/SOURCE and
38#    perform "document_changes",
39# b) or call "document_changes" directly and add the path to the source code as
40#    argument
41#    (e.g. document_changes current_version/trunk/SOURCE)
42#
43# Note:
44# The script will only work properly if the two following conditions are met:
45# 1) the 2nd line after "Current Revisions:" must contain text,
46# 2) the last line before "Former Revisions:" must not contain text.
