Module documentation for 1.6.18.0
This package contains libraries for dealing with system processes.
The typed-process package is a more recent take on a process API, which uses this package internally. It features better binary support, easier concurrency, and a more composable API. You can read more about it at https://github.com/fpco/typed-process/#readme.
