+# 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:
+#
+#    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
+
+set __git_tcsh_completion_original_script = ${HOME}/.git-completion.bash
+set __git_tcsh_completion_script = ${HOME}/.git-completion.tcsh.bash
+
+cat << EOF > ${__git_tcsh_completion_script}
+#!bash
+#
+# This script is GENERATED and will be overwritten automatically.
+# Do not modify it directly.  Instead, modify the git-completion.tcsh
+# script provided by Git core.
+#

+# Set COMP_WORDS in a way that can be handled by the bash script.
+COMP_WORDS=(\$1)
+
+# The cursor is at the end of parameter #1.
+# We must check for a space as the last character which will
+# tell us that the previous word is complete and the cursor
+# is on the next word.
+if [ "\${1: -1}" == " " ]; then
+       # The last character is a space, so our location is at the end
+       # of the command-line array
+       COMP_CWORD=\${#COMP_WORDS[@]}
+else
+       # The last character is not a space, so our location is on the
+       # last word of the command-line array, so we must decrement the
+       # count by 1
