@hackage vk-posix-pty0.2.1

This package simplifies the creation of subprocesses that interact with their parent via a pseudo terminal (see man pty).

Included ptywrap utility spawns a process with a pty, forwards its output to stdout as plain text without buffering and forwards the exit code. Note that it does not handle standard input.
