4Subject: [PATCH 3/7] Add argp implementation
5
6Argp is an advanced support for parsing unix-style argument vectors.
7In addition to the common getopt interface, it provides automatic
8response
9to `--help' and `--version' options and use of custom parser in
10conjunction
11with argp native option parser, among others.
12Argp support is required by elfutils package and prelink.
13
14In uClibc argp functionalities has been moved from C library to
15libuargp.so
16Further the libc.so linker script contains an AS_NEEDED entry so that
17it doesn't need to link libuargp.so explicitely.

837+ If the caller did not specify anything,
838+ the default is REQUIRE_ORDER if the environment variable
839+ POSIXLY_CORRECT is defined, PERMUTE otherwise.
840+
841+ REQUIRE_ORDER means don't recognize them as options;
842+ stop option processing when the first non-option is seen.
843+ This is what Unix does.
844+ This mode of operation is selected by either setting the environment
845+ variable POSIXLY_CORRECT, or using `+' as the first character
846+ of the list of option characters.
847+
848+ PERMUTE is the default. We permute the contents of ARGV as we
849+ scan, so that eventually all the non-options are at the end.
850+ This allows options to be given in any order, even with programs
851+ that were not written to expect this.
852+
853+ RETURN_IN_ORDER is an option available to programs that were
854+ written to expect options and other ARGV-elements in any order
855+ and that care about the ordering of the two. We describe each
856+ non-option ARGV-element as if it were the argument of an option
857+ with character code 1. Using `-' as the first character of the
858+ list of option characters selects this mode of operation.
859+
860+ The special argument `--' forces an end of option-scanning regardless
861+ of the value of `ordering'. In the case of RETURN_IN_ORDER, only
862+ `--' can cause `getopt' to return -1 with `optind' != ARGC. */

5005+/* Argp example #3 -- a program with options and arguments using argp */
5006+
5007+/* This program uses the same features as example 2, and uses options and
5008+ arguments.
5009+
5010+ We now use the first four fields in ARGP, so here's a description of them:
5011+ OPTIONS -- A pointer to a vector of struct argp_option (see below)
5012+ PARSER -- A function to parse a single option, called by argp
5013+ ARGS_DOC -- A string describing how the non-option arguments should look
5014+ DOC -- A descriptive string about this program; if it contains a
5015+ vertical tab character (\v), the part after it will be
5016+ printed *following* the options
5017+
5018+ The function PARSER takes the following arguments:
5019+ KEY -- An integer specifying which option this is (taken
5020+ from the KEY field in each struct argp_option), or
5021+ a special key specifying something else; the only
5022+ special keys we use here are ARGP_KEY_ARG, meaning
5023+ a non-option argument, and ARGP_KEY_END, meaning
5024+ that all arguments have been parsed
5025+ ARG -- For an option KEY, the string value of its
5026+ argument, or NULL if it has none
5027+ STATE-- A pointer to a struct argp_state, containing
5028+ various useful information about the parsing state; used here
5029+ are the INPUT field, which reflects the INPUT argument to
5030+ argp_parse, and the ARG_NUM field, which is the number of the
5031+ current non-option argument being parsed
5032+ It should return either 0, meaning success, ARGP_ERR_UNKNOWN, meaning the
5033+ given KEY wasn't recognized, or an errno value indicating some other
5034+ error.
5035+
5036+ Note that in this example, main uses a structure to communicate with the
5037+ parse_opt function, a pointer to which it passes in the INPUT argument to
5038+ argp_parse. Of course, it's also possible to use global variables
5039+ instead, but this is somewhat more flexible.
5040+
5041+ The OPTIONS field contains a pointer to a vector of struct argp_option's;
5042+ that structure has the following fields (if you assign your option
5043+ structures using array initialization like this example, unspecified
5044+ fields will be defaulted to 0, and need not be specified):
5045+ NAME -- The name of this option's long option (may be zero)
5046+ KEY -- The KEY to pass to the PARSER function when parsing this option,
5047+ *and* the name of this option's short option, if it is a
5048+ printable ascii character
5049+ ARG -- The name of this option's argument, if any
5050+ FLAGS -- Flags describing this option; some of them are:
5051+ OPTION_ARG_OPTIONAL -- The argument to this option is optional
5052+ OPTION_ALIAS -- This option is an alias for the
5053+ previous option
5054+ OPTION_HIDDEN -- Don't show this option in --help output
5055+ DOC -- A documentation string for this option, shown in --help output
5056+
5057+ An options vector should be terminated by an option with all fields zero. */
