###

## This should normally go in the ~/.bashrc file of your kde development user.

# Tell many scripts how to switch from source dir to build dir:

# If you don't have makeobj, install the package named kdesdk-scripts or
# kdesdk, or check out kdesdk/scripts from svn, or just don't set the alias
# yet.
