Because I'm making progress with Bash, and I don't have much desire to take on a project like this with a lnguage I know nothing about. Lua isn't going to be any better anyway...it's a text editing project, best suited for tools like sed and awk.
I was making some progress...I got to a point where I had defined one layer of submenus, and it should be fairly downhillish from here.
However, I'm dumping the project for a little while because of something I noticed in Ion3...it sucks with menu items which have dots in them....it completely chokes on the file and reverts to the default menu. This is unacceptable. I don't recall Ion2 doing this, so I'm going to go back to that one....but only after I stop grumbling about it. Ion3 has some big improvements apart from that glitch.
Clacker: I'm using sed mostly.
This is the bulk of what I have at this point.
The "append_exec_entry" function is what converts fluxbox [exec] lines into Ion format, except that I use awk to remove the '[exec]' part in another section of the script. I overlooked it in the function and just threw it in at the place I was currently working....I'll fix that eventually. The SUBLEVEL variable really doesn't serve much purpose right now...That's what I'm hoping to use to organize the submenu items in the main menu.

please make sure the 'TMP_DIR' variable in
\033[0;31m$0\033[0m
points to a writeable directory."
exit 1
