commit f0ccce855bd99fca7cfbbcafe3544e3113fedc67
Author: Werner Koch <wk at gnupg.org>
Date: Mon Aug 31 20:33:44 2015 +0200
gpgme-tool: Switch to argparse.c for option parsing.
* src/argparse.c, src/argparse.h: New. Taken from current gnupg.
* src/Makefile.am (gpgme_tool_SOURCES): New.
* src/gpgme-tool.c: Remove all argp.h stuff.
(my_strusage): New.
(main): Change to use argparse.
--
As a GnuPG related tool the user should get the same experience in
option parsing as with gpg et al. Thus we use the same parser.

+ *
+ * @Description
+ * This is my replacement for getopt(). See the example for a typical usage.
+ * Global flags are:
+ * Bit 0 : Do not remove options form argv
+ * Bit 1 : Do not stop at last option but return other args
+ * with r_opt set to -1.
+ * Bit 2 : Assume options and real args are mixed.
+ * Bit 3 : Do not use -- to stop option processing.
+ * Bit 4 : Do not skip the first arg.
+ * Bit 5 : allow usage of long option with only one dash
+ * Bit 6 : ignore --version
+ * all other bits must be set to zero, this value is modified by the
+ * function, so assume this is write only.
+ * Local flags (for each option):
+ * Bit 2-0 : 0 = does not take an argument
+ * 1 = takes int argument
+ * 2 = takes string argument
+ * 3 = takes long argument
+ * 4 = takes ulong argument
+ * Bit 3 : argument is optional (r_type will the be set to 0)
+ * Bit 4 : allow 0x etc. prefixed values.
+ * Bit 6 : Ignore this option
+ * Bit 7 : This is a command and not an option
+ * You stop the option processing by setting opts to NULL, the function will
+ * then return 0.
+ * @Return Value
+ * Returns the args.r_opt or 0 if ready
+ * r_opt may be -2/-7 to indicate an unknown option/command.
+ * @See Also
+ * ArgExpand
+ * @Notes
+ * You do not need to process the options 'h', '--help' or '--version'
+ * because this function includes standard help processing; but if you
+ * specify '-h', '--help' or '--version' you have to do it yourself.
+ * The option '--' stops argument processing; if bit 1 is set the function
+ * continues to return normal arguments.
+ * To process float args or unsigned args you must use a string args and do
+ * the conversion yourself.
+ * @Example
+ *
+ * ARGPARSE_OPTS opts[] = {
+ * { 'v', "verbose", 0 },
+ * { 'd', "debug", 0 },
+ * { 'o', "output", 2 },
+ * { 'c', "cross-ref", 2|8 },
+ * { 'm', "my-option", 1|8 },
+ * { 300, "ignored-long-option, ARGPARSE_OP_IGNORE},
+ * { 500, "have-no-short-option-for-this-long-option", 0 },
+ * {0} };
+ * ARGPARSE_ARGS pargs = { &argc, &argv, 0 }
+ *
+ * while( ArgParse( &pargs, &opts) ) {
+ * switch( pargs.r_opt ) {
+ * case 'v': opt.verbose++; break;
+ * case 'd': opt.debug++; break;
+ * case 'o': opt.outfile = pargs.r.ret_str; break;
+ * case 'c': opt.crf = pargs.r_type? pargs.r.ret_str:"a.crf"; break;
+ * case 'm': opt.myopt = pargs.r_type? pargs.r.ret_int : 1; break;
+ * case 500: opt.a_long_one++; break
+ * default : pargs.err = 1; break; -- force warning output --
+ * }
+ * }
+ * if( argc > 1 )
