# A little helper for copying built tests into an implementation's repo, for

|
|
# 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).

Specify a destination directory to receive copied tests. If not present,

the script runs in dry-run mode and does not copy files.

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\`.

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\`.
