5*bcb5dc79SHONG Yifannative.genrule() is sometimes used to copy files (often wishing to rename them).
6*bcb5dc79SHONG YifanThe 'copy_file' rule does this with a simpler interface than genrule.

29*bcb5dc79SHONG Yifan| Name  | Description | Default Value |
30*bcb5dc79SHONG Yifan| :------------- | :------------- | :------------- |
31*bcb5dc79SHONG Yifan| <a id="copy_file-name"></a>name |  Name of the rule.   |  none |
32*bcb5dc79SHONG Yifan| <a id="copy_file-src"></a>src |  A Label. The file to make a copy of. (Can also be the label of a rule that generates a file.)   |  none |
33*bcb5dc79SHONG Yifan| <a id="copy_file-out"></a>out |  Path of the output file, relative to this package.   |  none |
34*bcb5dc79SHONG Yifan| <a id="copy_file-is_executable"></a>is_executable |  A boolean. Whether to make the output file executable. When True, the rule's output can be executed using `bazel run` and can be in the srcs of binary and test rules that require executable sources. WARNING: If `allow_symlink` is True, `src` must also be executable.   |  `False` |
35*bcb5dc79SHONG Yifan| <a id="copy_file-allow_symlink"></a>allow_symlink |  A boolean. Whether to allow symlinking instead of copying. When False, the output is always a hard copy. When True, the output *can* be a symlink, but there is no guarantee that a symlink is created (i.e., at the time of writing, we don't create symlinks on Windows). Set this to True if you need fast copying and your tools can handle symlinks (which most UNIX tools can).   |  `False` |
36*bcb5dc79SHONG Yifan| <a id="copy_file-kwargs"></a>kwargs |  further keyword arguments, e.g. `visibility`   |  none |
