# A little helper for copying built tests into an implementation's repo, for
# testing changes.
#
# The destination directory is specified with `-d`, `--dest` or `--destination`.
# Source files can be positional (in which case, they are ignored if not found
# to be relative to the test directory), or specified via utilities such as
# `--head` (tests changed in the current working directory), or `--since N`
# (tests changed in the last N commits).

Help:
-d <argument> | -d=<argument>
--dest <argument> | --dest=<argument>
--destination <argument> | --destination=<argument>
Specify a destination directory to receive copied tests. If not present,
the script runs in dry-run mode and does not copy files.
-n
--dryrun
--dry-run
Don't copy files, but print the operations which would be performed.
Useful for debugging.
--head
Copy test files which have changed in the working directory since the
last commit. Performs \`git diff HEAD --name-only\`.
-s <argument> | -s=<argument>
--diff <argument> | --diff=<argument>
--since <argument> | --since=<argument>
Copy files which have changed in the past N commits. Also includes
changes in the current working directory since the last commit. Performs
\`git diff HEAD~\<argument> --name-only\`.
-h
--help
Print this help message.
