Timer Plasmoid Companion Script

Summary
I never really cared much for GUI alarm clocks - they always felt like time wasters when I could just run something like "sleep 30m && mplayer -loop 0 /path/to/sound.file" and be done with it. Then I discovered the outstanding Timer plasmoid that ships with KDE 4.2. It did have one big caveat though: in its current state, there's no convenient way to have it play a sound repeatedly until the user acknowledges the alarm (Yes, I know I could put the aforementioned MPlayer command in the command field, but then I'd have to open a terminal to kill mplayer).

So I did what I always do when I run into an easy problem like that - whipped up a hacky-tacky little script to "fix" it. By default, it uses MPlayer to loop /usr/share/sounds/KDE-Sys-App-Positive.ogg until the user clicks OK in the dialog window that pops up (it uses KDialog for this, hence it being on kde-apps.org). If you don't have MPlayer installed, or you don't like the sound it plays, feel free to change it.

I mostly made this so I could use it with the Timer plasmoid, but you can also run it stand-alone. Run "tpcs --help" for details.

Instructions
Download the script and put it in your path (~/.local/bin, for example, but make sure ~/.bash_profile contains this line: PATH=~/.local/bin:"${PATH}").
Optional
Tell the Timer plasmoid (or whatever other program you may want to call it from) to run tpcs, as shown in the first screenshot.

TODO
Make sure MPlayer and the default sound file exist on the user's system; offer option to change them.

I'm open to suggestions for anything else.
