Oh wow that is cool! I'll do this now and let you know. Ha Ha Ha -- well that turned into an extremely interesting little project. The long and short of it is that I can use your neat little tool now to get a dmenu deb but in order to do that I had to build from scratch a dmenu.deb. Perhaps I didn't but it was the only way I could get dmenu installed on my box so apt would see it as part of the apt system. You see I had just done a quick and dirty
make clean install
and then done my adjusting from there. So when I ran
dpkg-repack dmenu
the system said "whachyou talkin bout Willis" I know nothing of this dmenu.
dmenu would not build as a deb easily because ..... it doesn't come that way. Or at least I could not find it. So after about 100 ways that did not work I found
http://stackoverflow.com/questions/8003739/is-there-a-way-to-automatically-determine-dependencies-when-setting-up-a-dpkg-co in which the answers lay. Outstanding stuff by that guy.
Anyway it created an opportunity. I disliked the way my install was and this allowed me to build it to install dmenu and stest to where I want and I can easily add packages and scripts to the install (now that I know what I am doing) as anyone sees fit to suggest. e.g. I built it so dmenu and stest go into /usr/bin and dmenu_run which is what matters goes into /usr/local/sbin but that is essentially trivial to adjust at this point. I also was able to create and use any dmenu_run of my choice (although I used the one from the Arch Forum for this build). VastOne can't thank you enough for sending me on this little errand. I learned a lot (mostly more about how little I really know) but good stuff.
In the end I did use your tool but after I had already done the install and had a deb. I am attaching the one built with repack named dmenu_4.5.2_amd64.deb. It is version .2 and my initial build from source is dmenu-4.5.1.deb just to keep them straight.
Finally if anyone has read this far and is interested. If there are dmenu tweaks that you would like to have in the Vsido version you can either pass them along to me

then I can have them or follow the instructions on the link and build your own. Fun stuff!
PS - I haven't tested the repack on my system due to time constraints, the original version kept the proper ownerships of files etc. Both should work the same though I would expect. One more thing you might want to put a hold on dmenu so it doesn't get updated by Sid and you lose you settings.
