+# 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% tcsh_completion.sh FILE
+#    tcsh% source FILE
+#
+# If FILE is not specified, tcsh_completion will be generated.
+#
+# Bugs:
+# ----
+# 1. command specific options are not supported
+# 2. hg commands must be specified immediately after 'hg'.
