There are situations in test scripts where we want to keep open file descriptors while performing other commands. Bash has abilities to manage file descriptors by numbers, but the syntax is a little brain damaging. This library provides wrappers around it to abstract away bash's syntax and also provides a helper function to pick a free file descriptor on the fly. The APIs are pretty self explanatory.
