Execute and control OS processes from Erlang/OTP.
This project implements a C++ port program and Erlang application that gives light-weight Erlang processes fine-grain control over execution of OS processes.
It makes possible for an Erlang process to start, stop an OS process,
send POSIX signals, know process IDs of the started OS process, set up
a monitor and/or link to it, run interactive commands with pseudo
terminals. This application provides better control
over OS processes than built-in erlang:open_port/2 command with a
{spawn, Command} option, and performs proper OS child process cleanup
when the emulator exits.

Linux, Solaris, MacOS X
See http://saleyn.github.io/erlexec
Make sure you have rebar (http://github.com/basho/rebar or http://github.com/basho/rebar3) installed locally and the rebar script is in the path.
If you are deploying the application on Linux and would like to take advantage of exec-port running tasks using effective user IDs different from the real user ID that started exec-port, then make sure that libcap-dev[el] library is installed.
OS-specific libcap-dev installation instructions:
- Fedora, CentOS: "yum install libcap-devel"
- Ubuntu: "apt-get install libcap-dev"
