   8# When sourced, this script will generate a new script that uses
   9# the git-completion.bash script provided by core Git.  This new
  10# script can be used by tcsh to perform git completion.
  11# The current script also issues the necessary tcsh 'complete'
  12# commands.
  13#
  14# To use this completion script:
  15#
  16#    1) Copy both this file and the bash completion script to ${HOME}.
  17#       You _must_ use the name ${HOME}/.git-completion.bash for the
  18#       bash script.
  19#       (e.g. ~/.git-completion.tcsh and ~/.git-completion.bash).
  20#    2) Add the following line to your .tcshrc/.cshrc:
  21#        source ~/.git-completion.tcsh
  22#    3) For completion similar to bash, it is recommended to also
  23#       add the following line to your .tcshrc/.cshrc:
  24#        set autolist=ambiguous
  25#       It will tell tcsh to list the possible completion choices.
  26
  27set __git_tcsh_completion_original_script = ${HOME}/.git-completion.bash
  28set __git_tcsh_completion_script = ${HOME}/.git-completion.tcsh.bash
  29
  30# Check that the user put the script in the right place
  31if ( ! -e ${__git_tcsh_completion_original_script} ) then
  32        echo "git-completion.tcsh: Cannot find: ${__git_tcsh_completion_original_script}.  Git completion will not work."
  33        exit
