Ok, i will implemented a basic GPSBabel interface using KProcess (like i use 
with dcraw in Raw Converter). 

There is already a GpsBabelBinary class witch detect if th eprogram is 
installed into the computer, and if we have the right version.

The problem with gpsbabel is the inpout format recognition. We _must_ set the 
right inpout format before to convert data. There is no auto-detect format 
like with dcraw for example.

I'm waiting your indeep comments about gps format investiguations.

Are you get a KDE svn account ?
