3 * aka "2wm" - too weak menu, two week menu, akin to twm
5 * Craig wants a super minimal menu ASAP before launch, so lets see what I can put together in 2 weeks with not much
6 * free time ;) I'd like to do a fuller ('tiny', but with plugin support and a decent expansion and customizing design..)
11 /* mmenu - This is the actual menu
12 * The goal of this app is to show a application picker screen of some sort, allow the user to perform some useful
13 * activities (such as set clock speed, say), and request an app to run, or shutdown, etc.
14 * To keep the memory footprint down, when invoking an application, the menu _exits_, and simply spits out
15 * an operation for mmwrapper to perform. In the case of no wrapper, the menu will just exit, which is handy for
20 * 1) determine app list (via pnd scan, .desktop scan, whatever voodoo)
21 * 2) show a menu, allow user to interact:
22 * a) user picks an application to run, or -> exit, pass shell run line to wrapper
23 * b) user requests menu shutdown -> exit, tell wrapper to exit as well
24 * c) user performsn some operation (set clock, copy files, whatever) -> probably stays within the menu
