# This script will print the depth path for a mozilla directory based

# Its a hack. Its brute force. Its horrible.
# It dont use Artificial Intelligence. It dont use Virtual Reality.
# Its not perl. Its not python. But it works.

# Usage: print-depth-path.sh
#
# Send comments, improvements, bugs to ramiro@netscape.com
#
# Make sure a Makefile.in exists
