Environment variables, their defaults and relative paths, where the default=
s=20
usually depend on paths specified at build time.

The main environment variable for this is KDEDIRS. Quite like PATH it is a=
=20
list of (colon separated) directories, where the order indicates the=20
respective priority.

Then, depending on the resource, there is an associated relative=20
path/subdirectory, e.g.

share/apps/
KDE application data

config/
KDE configs

lib/kde3  (lib/kde4)
KDE plugins (as a resource called modules)

basically KDEHOME (default $HOME/.kde/) is also such a base directory, the =
one=20
with highest priority.

kde-config (kde4-config) is a nice command line tool which one can use to=20
determine such paths for example for using in scripts (the KDE start script=
=20
startkde uses this as well, at least it does in KDE3)

Cheers,
Kevin
