This program sets up a base kdesrc-build configuration to
use.

It can be modified as you wish later. Before the form is
presented, you will be asked if you would like an
explanation of the kdesrc-build file layout.  It is
recommended to read this if you are not already familiar
with building software.

kdesrc-build must download source code from the KDE
repositories.  This source code is then compiled, in the
"build directory". Once complete, this compiled code is
installed to its final location, the "install directory".

This program will only configure the install location, but
all directories are configurable.

The space requirements vary, but typically the build
directory will require 3-5 times as much space as the
corresponding source directory. The space required of
installed software will be less than the build directory.
