# Run GNU indent on sources. Don't run this unless all the sources compile cleanly.
#
# Whole idea:
#   1. Check for .indent.pro, otherwise indent will use unknown
#      settings, or worse, the GNU defaults.)
#   2. Check that this is GNU indent.
#   3. Make sure to process only the NON-generated .c and .h files.
#   4. Run indent twice per file. The first time is a test.
#      Otherwise, indent overwrites your file even if it fails!
