"""native_binary() and native_test() rule implementations.
|
|
|
|
These rules let you wrap a pre-built binary or script in a conventional binary
|
|
and test rule respectively. They fulfill the same goal as sh_binary and sh_test
|
|
do, but they run the wrapped binary directly, instead of through Bash, so they
|
|
don't depend on Bash and work with --shell_exectuable="".
