## Build-time customization

# User-facing executable Python code
# MyPaint app
env.Command('mypaint', 'mypaint.py', [burn_versions, Chmod('$TARGET', 0755)])
AlwaysBuild('mypaint') # especially if the "python_binary" option was changed

# Thumbnailer script
env.Command('desktop/mypaint-ora-thumbnailer', 'desktop/mypaint-ora-thumbnailer.py', [burn_versions, Chmod('$TARGET', 0755)])
AlwaysBuild('desktop/mypaint-ora-thumbnailer')


## Additional cleanup

env.Clean('.', Glob('gui/*.pyc'))
