Item11171: developer script to fix up TOPICINFO

Ugly - but was useful to fix up the topicinfo lines - removing the
$Rev$, updating version, author, date, and removing comment and reprev.

Item11171: Issues with script and untracked files

Also run instructions were wrong.

Synced from Trunk, Rev 12751 and 12757
