Disable "A version with the same tree already is installed somewhere" optimization when the script is run with --force. Also be careful when crafting "--root=/dev/shm/testpen" option to the test scripts; on Ubuntu, /dev/shm may be a symbolic link that points at /run/shm, and "$TRASH_DIRECTORY" and $(pwd) may not match, causing poorly written tests to fail.
The compare-cooking.perl script is meant to help viewing the differences
between periodical "What's cooking" messages, and can be used as an
external diff driver by:
$ git config diff.whatscooking.command ./compare-cooking.perl
to produce this section in your .git/config
[diff "whatscooking"]
command = ./compare-cooking.perl
You can use e.g.
$ git log -p --ext-diff whats-cooking.txt
$ git show --ext-diff whats-cooking.txt
to review the history.
