#
# Description
#     Build the tags files for all the .C and .H files
#
#     This script is designed for use with emacs
#
#     For use, download/install 'exuberant ctags'.  The executable for this
#     package is called ctags, which conflicts with the 'standard' version
#     of ctags found on most *nix systems.  Rename the exuberant ctags
#     executable to ectags.
