A rule that writes a UTF-8 encoded text file from user-specified contents.
native.genrule() is sometimes used to create a text file. The 'write_file' and
macro does this with a simpler interface than genrule.
The rules generated by the macro do not use Bash or any other shell to write the
file. Instead they use Starlark's built-in file writing action
(ctx.actions.write).
## write_file
write_file(name, out, content, is_executable, newline, kwargs)
Creates a UTF-8 encoded text file.
**PARAMETERS**

| name | Name of the rule. | none |
