Welcome to UltraGetopt

UltraGetopt is a replacement for getopt() with support for many common
extensions, MS-DOS formatted option strings, and much more.  UltraGetopt is
free software.  Please see the file COPYING for details.  For building,
installation, and usage instructions please see the INSTALL file.

			    ==== DEFINES ====
When compiling ultragetopt.c, there are several defines that change the default
behavior of the (ultra)getopt functions.

Meta-options:
These options will set the other options below to appropriate values to mimic
the functionality of other getopt suites.
ULTRAGETOPT_LIKE_BSD
	Behave like BSD getopt()
ULTRAGETOPT_LIKE_DARWIN
	Behave like Darwin (Mac OS) getopt()
ULTRAGETOPT_LIKE_GNU
	Behave like GNU getopt()
ULTRAGETOPT_LIKE_POSIX 
	Behave like POSIX definition of getopt()

Compiletime-only Behavior Options:
These options change the default behavior of getopt() and do not have a
corresponding runtime flag (although they may be affected by other arguments).
ULTRAGETOPT_ASSIGNSPACE
	Parse "-o value" as "value" rather than " value"
	Note: Only applicable when argv[x] == "-o value", not for
	      argv[x] == "-o" [x+1] == "value"
ULTRAGETOPT_NO_OPTIONALARG
	Do not support GNU "::" optional argument.
	Note:  Always supported in *_long*() functions.
ULTRAGETOPT_NO_OPTIONASSIGN
	Do not support --option=value syntax

Runtime-selectable options:
These options can all be selected by passing their value as a flag to the
ultragetopt_tunable() function, where ULTRAGETOPT_ is replaced by UGO_ for
compactness of the source.  Defining these values sets the default state of
the flag when invoked from ultragetopt{_long,_dos}().
ULTRAGETOPT_DEFAULTOPTOPT
	Set optopt to this value by default on each call to getopt()
ULTRAGETOPT_HYPHENARG
	Accept -option -arg as -option with argument "-arg" rather than -option
	missing argument
ULTRAGETOPT_LONGOPTADJACENT
	Accept adjacent arguments to long options (e.g. --optionarg) based on
	first longest-match
ULTRAGETOPT_OPTIONPERMUTE
	Permute options, do not stop at first non-option.   A leading '+' in
	shortopts or when the $POSIXLY_CORRECT environmental variable are set,
	permuting will be stopped @ runtime
ULTRAGETOPT_SHORTOPTASSIGN
	Support -o=file syntax for short options
ULTRAGETOPT_SEPARATEDOPTIONAL
	Accept separated optional arguments.  Parse -o file as -o with argument
	file rather than -o without an argument and non-option argument "file"
ULTRAGETOPT_DOS_DASH
	Support - and -- options in ultragetopt*_dos() functions
ULTRAGETOPT_NO_EATDASHDASH
	Do not increment optind when argv[optind] is -- as required by SUS/POSIX

Error message options:
These options change the formatting of the error messages produced by
ultragetopt.
ULTRAGETOPT_BSD_ERRORS
	Print error messages matching BSD getopt
ULTRAGETOPT_DARWIN_ERRORS
	Print error messages matching Darwin getopt
ULTRAGETOPT_GNU_ERRORS
	Print error messages matching GNU getopt
