Detailed Description

Getting started with reading this source code. The source is mainly divided into four parts:

1. Exception Classes: These are very basic exception classes derived from runtime_error exception. There are two types of exception thrown from subprocess library: OSError and CalledProcessError
2. Popen Class This is the main class the users will deal with. It provides with all the API's to deal with processes.
3. Util namespace It includes some helper functions to split/join a string, reading from file descriptors, waiting on a process, fcntl options on file descriptors etc.
4. Detail namespace This includes some metaprogramming and helper classes.
