@node getopt-long
@section The (ice-9 getopt-long) Module
The @code{(ice-9 getopt-long)} facility is designed to help parse
arguments that are passed to Guile programs on the command line, and is
modelled after the C library's facility of the same name
(@pxref{Getopt,,,libc,The GNU C Library Reference Manual}). For a more
low-level interface to command-line argument parsing, @xref{SRFI-37}.
The @code{(ice-9 getopt-long)} module exports two procedures:
@code{getopt-long} and @code{option-ref}.
