# Description

# -----------

# This script generates a tcsh source file to support completion

# of Mercurial commands and options.

#

# Instruction:

# Run this script to generate the tcsh source file, and source

# the file to add command completion support for Mercurial.

#

#    tcsh% source FILE

# 1. command specific options are not supported

# 2. hg commands must be specified immediately after 'hg'.
