Subject: Check the data path before usage
X-Git-Tag: 0.2.20110731_3~50^2~11^2~1^2~1

Check the data path before usage

When not running in place, check if the assumed data path in
../share/APPNAME exists. If it doesn't exist, fall back to ../data
instead. This allows the program to run successfully from the checkout
directory even without the run-in-place flag active.
