BTW, I have some questions about modules:
1. if I want to know how many modules I have right now, just look the
'*.a, *.la" files in plugins right?
2. can I expand them later separately instead of re-installing lttv all again?
3. is there any doc or any commands that can tell me how to use and
what each plugin do for?
appreciate your help,
miloody
