Checkout the project:
git clone git@github.com:ocean90/gdvk-abschproj.git
After that it's required to setup some linebreak-correction filters which ensure that the actionscript files are commited correctly.
This is required because it isn't possible to checkin some git configuration parameters and the Adobe Flash Professional use the old MacOS 9 linebreak instead of standard unix linebreak (which use also OSX).
cd gdvk-abschproj
git config --add filter.cr.clean "tr '\r' '\n'"
git config --add filter.cr.smudge "tr '\n' '\r'"
Optional: Check the filter configuration:
cat .gitattributes
git config --list | grep filter
