Looking at the size of this thing compared to our audacity, I thought
to myself "hmm, that's a shell script" and sure enough

--8<---------------cut here---------------start------------->8---
#!/gnu/store/4y5m9lb8k3qkb1y9m02sw9w9a6hacd16-bash-minimal-5.1.8/bin/sh

lib="${0%/*}/lib/audacity"
share="${0%/*}/share/audacity"

export LD_LIBRARY_PATH="${lib}:${LD_LIBRARY_PATH}"
export AUDACITY_MODULES_PATH="${AUDACITY_MODULES_PATH}:${lib}/modules"
export AUDACITY_PATH="${AUDACITY_PATH}:${share}"

exec "${0%/*}/bin/audacity" "$@"

At the time of writing none of these appear particularly needed, though
if the time comes we might just port over the 'wrap-emacs-paths phase.

We can try searching for the bits in CMakeLists that install this
wrapper or we can simply drop the file.  WDYT?
