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.
