Sure, that's one solution.

Cool.

On the app dev side, I've written a first pass at a shell script that can be
run from inside a project to build an app bundle.

It assume make is being used, that there is a make install rule, and that
the make install rule properly handles  make prefix=blah/blah install

http://pastie.org/597905

It will generate `basename `pwd``.app in the current directory, with the
correct layout, and a wrapper script to set up the environment.

I have tested it on my patched version of Hedgewars (patched to use
XDG_DATA_DIRS and PATH for relocation) and it's worked marvelously.

Using a wrapper script to set up the env has many benefits.  It remains
compatible with MacOS (which does not set the env vars we're interested in)
and also means that you can easily invoke the script from the command line
(if you invoke it with its full path).  Also, app devs may wish to have a
slightly different env, and could therefore create their own wrapper script
if they desired.
