IGC files & Linux

I like KFLOG very much but the application needs data files.

What concerns ground or map terrain, the old file published in 2001
are still OK. Terrains do not change as fast as the weather....

But what concerns the use of waypoints and airspace, the files seems
to be designed for the very fisrt version of KFLOG. I has some
problems running KFLOG with those.

Another point, is the fact that data files have a kfl extension. What
is the content of this file? The file format in not yet clear to me. I
had the idea to manually updated those files.
As I don't know how the data format is designed, it is nearly
impossible to have fresh data.

Another missing functionality is the lack of engine noise reading.
But I still needs a few days to play with the tool to analyse it
further into the details.
