#ifndef OPTPARSE_H
#define OPTPARSE_H
/**
* Optparse -- portable, reentrant, embeddable, getopt-like option parser
*
* The POSIX getopt() option parser has three fatal flaws. These flaws
* are solved by Optparse.
*
* 1) Parser state is stored entirely in global variables, some of
* which are static and inaccessible. This means only one thread can
* use getopt(). It also means it's not possible to recursively parse
* nested sub-arguments while in the middle of argument parsing.
* Optparse fixes this by storing all state on a local struct.
*
* 2) The POSIX standard provides no way to properly reset the parser.
* This means for portable code that getopt() is only good for one
* run, over one argv with one optstring. It also means subcommand
* options cannot be processed with getopt(). Most implementations
* provide a method to reset the parser, but it's not portable.
* Optparse provides an optparse_arg() function for stepping over
* subcommands and continuing parsing of options with another
* optstring. The Optparse struct itself can be passed around to
* subcommand handlers for additional subcommand option parsing. A
* full reset can be achieved by with an additional optparse_init().
*
* 3) Error messages are printed to stderr. This can be disabled with
* opterr, but the messages themselves are still inaccessible.
* Optparse solves this by writing an error message in its errmsg
* field. The downside to Optparse is that this error message will
* always be in English rather than the current locale.
*
* Optparse should be familiar with anyone accustomed to getopt(), and
* it could be a nearly drop-in replacement. The optstring is the same
* and the fields have the same names as the getopt() global variables
* (optarg, optind, optopt).
*
* Optparse also supports GNU-style long options with optparse_long().
* The interface is slightly different and simpler than getopt_long().
*
* By default, argv is permuted as it is parsed, moving non-option
* arguments to the end. This can be disabled by setting the `permute`
* field to 0 after initialization.

## There are various ways to get dependency output from gcc. Here's
## why we pick this rather obscure method:
## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say). Also, it might not be
## supported by the other compilers which use the 'gcc' depmode.
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the "deleted header file" problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.
## Some versions of gcc put a space before the ':'. On the theory
## that the space means something, we add a space to the output as
## well. hp depmode also adds that space, but also prefixes the VPATH
## to the object. Take care to not repeat it in the output.
## Some versions of the HPUX 10.20 sed can't process this invocation
## correctly. Breaking it into two sed invocations is a workaround.
