[1326] | 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. |
