+# When sourced, this script will generate a new script that uses
+# the git-completion.bash script provided by core Git. This new
+# script can be used by tcsh to perform git completion.
+# The current script also issues the necessary tcsh 'complete'
+# commands.
+#
+# To use this completion script:
+#
+# 0) You need tcsh 6.16.00 or newer.
+# 1) Copy both this file and the bash completion script to ${HOME}.
+# You _must_ use the name ${HOME}/.git-completion.bash for the
+# bash script.
+# (e.g. ~/.git-completion.tcsh and ~/.git-completion.bash).
+# 2) Add the following line to your .tcshrc/.cshrc:
+# source ~/.git-completion.tcsh
+# 3) For completion similar to bash, it is recommended to also
+# add the following line to your .tcshrc/.cshrc:
+# set autolist=ambiguous
+# It will tell tcsh to list the possible completion choices.
