enditem()
The tt(compdef) function is the place to turn to when one wants to
define what the completion system should complete for a certain
command. The function named can of course be one of the functions
supplied or one written by the user. For example, if one has a
command tt(foo) that gets process identifiers as arguments, one could
do:
example(compdef _pids foo)
using the tt(_pids) function from the distribution to generate the
process identifiers. Not also the tt(_use_lo) function described
below, which can be used to complete options for commands that
understand the `tt(-)tt(-help)' option.

Like tt(_tags) this function supports the tt(-C) option to give a
different name for the argument context field.

This function is a simple wrapper around the tt(_arguments) function
described below. It can be used to automatically complete long
options for commands that understand the `tt(-)tt(-help)' option
(`tt(_use_lo)' is for `use long options'). It is not intended to be
used from completion functions but as a top-level completion function
in its own right. For example, to enable option completion for the
commands tt(foo) and tt(bar), one would call:
example(compdef _use_lo foo bar)
in one of the initialization files after the call to tt(compinit).
The default installation uses this function only to generate
completions for some GNU-commands because to complete the options, the
command has to be called and hence it shouldn't be used if one can't
be sure that the command understands the `tt(-)tt(-help)' option.
