-| hardlink | Controls when to use hardlinks to files instead of making copies.
Creating hardlinks is much faster than making copies of files with the caveat that hardlinks share file permissions with their source.
Since Bazel removes write permissions on files in the output tree after an action completes, hardlinks to source files are not recommended since write permissions will be inadvertently removed from sources files.

-| include_external_repositories | List of external repository names (with glob support) to include in the output directory.
Files from external repositories are only copied into the output directory if the external repository they come from matches one of the external repository patterns specified or if they are in the same external repository as this target.
When copied from an external repository, the file path in the output directory defaults to the file's path within the external repository. The external repository name is _not_ included in that path.
For example, the following copies @external_repo//path/to:file to path/to/file within the output directory.
copy_to_directory( name = "dir", include_external_repositories = ["external_*"], srcs = ["@external_repo//path/to:file"], )
Files that come from matching external are subject to subsequent filters and transformations to determine if they are copied and what their path in the output directory will be. The external repository name of the file from an external repository is not included in the output directory path and is considered in subsequent filters and transformations.

-| replace_prefixes | Map of paths prefixes (with glob support) to replace in the output directory path when copying files.
If the output directory path for a file starts with or fully matches a a key in the dict then the matching portion of the output directory path is replaced with the dict value for that key. The final path segment matched can be a partial match of that segment and only the matching portion will be replaced. If there are multiple keys that match, the longest match wins.
Forward slashes (/) should be used as path separators.
Replace prefix transformation are the final step in the list of filters and transformations. The final output path of a file being copied into the output directory is determined at this step.
Globs are supported (see rule docstring above). | Dictionary: String -> String | optional | {} |
-| root_paths | List of paths (with glob support) that are roots in the output directory.
If any parent directory of a file being copied matches one of the root paths patterns specified, the output directory path will be the path relative to the root path instead of the path relative to the file's workspace. If there are multiple root paths that match, the longest match wins.
Matching is done on the parent directory of the output file path so a trailing '**' glob patterm will match only up to the last path segment of the dirname and will not include the basename. Only complete path segments are matched. Partial matches on the last segment of the root path are ignored.
Forward slashes (/) should be used as path separators.

Therefore if size is specified, we should allow timeout to take its implied default.
If neither is set, then we can fix Bazel's wrong default here to avoid warnings under
