Basically, 'compgen' is the workhorse that lets you generate completion
candidates and convert it into a list of lines that you can then further
process, used heavily within custom completion libraries.  I'll leave it
to you to read 'help compgen' to see which options you need to pass.  If
you have a custom completion library installed, such as the
'bash-completion' package, you may find that 'set -vx' prior to hitting
TAB will give you some insight into how compgen is called.
