How can I force subversion to commit an unchanged file?

Question

I want subversion to commit a file even if it\'s unchanged. Is there a way to do this?

Answer 1

Answering some people questioning this should be possible: for some reason svn doesn't recognizes differences between doc files, so I would like to force commit as well!

I am now moving documentation from static dirs, to svn. files are like UG_v1.2, UG_v1.3 etc. So just to keep history, I take 1.2, remove version from the filename and add and commit it to svn. Then I take the ver from the second one, copy it over the first one and want to commit it and newer version. File size and creation date changes (not mentioning what's inside the doc), but svn claims it's perfectly the same file and disallows me to commit. When I manually change the doc, svn sees the different. The heck? :>
