-  Since v2.04, bash has allowed you to intelligently program and extend its
-  standard completion behavior to achieve complex command lines with just a
-  few keystrokes. Imagine typing ssh [Tab] and being able to complete on hosts
-  from your ~/.ssh/known_hosts files. Or typing man 3 str [Tab] and getting a
-  list of all string handling functions in the UNIX manual. mount system:
-  [Tab] would complete on all exported file-systems from the host called
-  system, while make [Tab] would complete on all targets in Makefile. This
-  project was conceived to produce programmable completion routines for the
-  most common Linux/UNIX commands, reducing the amount of typing sysadmins and
-  programmers need to do on a daily basis.
