If you did some modification in Linuxconf and want to contribute them,
the easiest way is to send a diff file so the maintainer can easily
see what you did and apply your changes to the development tree.
Here is a quick recipe to produce a diff file:
Untar the original source (1.17r9 in this example).
Rename it to linuxconf-1.17r9-new.
Do your modifications there and test them.
Once ready to build a diff, untar the original linuxconf 1.17r9
Now you have side by side in the same directory, linuxconf-1.17r9
and linuxconf-1.17r9-new sub-directories.
