You have to "merge", not "delete": cvs update -j 1.8 -j 1.3 filename will "undo" changes made between 1.3 and 1.8. Note it won't bring back the revision number 1.3, because once assigned revision number won't go back. But the new revision will be identical to 1.3. There will be track of what happened - user X made changes that user Y later had to get rid of and return to a previous revision code. -- Luigi D. Sandon
