Unix subprocess manager for Erlang
2+
==================================
3+
4+
`subproc` is a unix subprocess manager for Erlang. It works much closer with
5+
operating systems than Erlang, so over built-in ports it provides several
6+
advantages:
7+
8+
* tracks subprocess' PID
9+
* can spawn a subprocess in a process group
10+
* can send a signal to a subprocess or its process group
11+
* subprocess' STDIO can be intercepted with `pipe(2)` or `socketpair(2)`
12+
* spawned port can work in `{active,once}` and passive modes known from
13+
`gen_tcp` and other socket modules, which provides a sensible backpressure
14+
to external command (running `yes` won't trigger OOM killer)
