/**
* Header file for the bproc launcher. This launcher is actually split into 2
* modules: pls_bproc & pls_bproc_orted. The general idea behind this launcher is:
* 1. pls_bproc is called by orterun. It figures out the process mapping and
* launches orted's on the nodes
* 2. pls_bproc_orted is called by orted. This module intializes either a pty or
* pipes, places symlinks to them in well know points of the filesystem, and
* sets up the io forwarding. It then sends an ack back to orterun.
* 3. pls_bproc waits for an ack to come back from the orteds, then does several
* parallel launches of the application processes. The number of launches is
* equal to the maximum number of processes on a node. For example, if there
* were 2 processes assigned to node 1, and 1 process asigned to node 2, we
* would do a parallel launch that launches on process on each node, then
* another which launches another process on node 1.
