PStreams allows you to run another program from your C++ application and to transfer data between the two programs,
similar to shell pipelines. In the simplest case, a PStreams class is like a C++ wrapper for the POSIX.2
functions popen(3) and pclose(3), using C++ IOStreams instead of C's stdio library.
The library provides class templates in the style of the standard IOStreams that can be used with any standard-conforming C++ compiler on a POSIX platform.
The classes use a streambuf class that uses fork() and the exec family of functions to create a new process and to write/read data to/from the process.
