-From eaae816fb22929469aa4cc3402b91b512fc69549 Mon Sep 17 00:00:00 2001
-From: Salvatore Cro <salvatore.cro@st.com>
-Date: Sun, 16 Aug 2015 20:53:37 -0700
-Subject: [PATCH 3/7] Add argp implementation
-
-Argp is an advanced support for parsing unix-style argument vectors.
-In addition to the common getopt interface, it provides automatic
-response
-to `--help' and `--version' options and use of custom parser in
-conjunction
-with argp native option parser, among others.
-Argp support is required by elfutils package and prelink.
-
-In uClibc argp functionalities has been moved from C library to
-libuargp.so
-Further the libc.so linker script contains an AS_NEEDED entry so that
-it doesn't need to link libuargp.so explicitely.

-+/* Argp example #3 -- a program with options and arguments using argp */
-+
-+/* This program uses the same features as example 2, and uses options and
-+ arguments.
-+
-+ We now use the first four fields in ARGP, so here's a description of them:
-+ OPTIONS -- A pointer to a vector of struct argp_option (see below)
-+ PARSER -- A function to parse a single option, called by argp
-+ ARGS_DOC -- A string describing how the non-option arguments should look
-+ DOC -- A descriptive string about this program; if it contains a
-+ vertical tab character (\v), the part after it will be
-+ printed *following* the options
-+
-+ The function PARSER takes the following arguments:
-+ KEY -- An integer specifying which option this is (taken
-+ from the KEY field in each struct argp_option), or
-+ a special key specifying something else; the only
-+ special keys we use here are ARGP_KEY_ARG, meaning
-+ a non-option argument, and ARGP_KEY_END, meaning
-+ that all arguments have been parsed
-+ ARG -- For an option KEY, the string value of its
-+ argument, or NULL if it has none
-+ STATE-- A pointer to a struct argp_state, containing
-+ various useful information about the parsing state; used here
-+ are the INPUT field, which reflects the INPUT argument to
-+ argp_parse, and the ARG_NUM field, which is the number of the
-+ current non-option argument being parsed
-+ It should return either 0, meaning success, ARGP_ERR_UNKNOWN, meaning the
-+ given KEY wasn't recognized, or an errno value indicating some other
-+ error.
-+
-+ Note that in this example, main uses a structure to communicate with the
-+ parse_opt function, a pointer to which it passes in the INPUT argument to
-+ argp_parse. Of course, it's also possible to use global variables
-+ instead, but this is somewhat more flexible.
-+
-+ The OPTIONS field contains a pointer to a vector of struct argp_option's;
-+ that structure has the following fields (if you assign your option
-+ structures using array initialization like this example, unspecified
-+ fields will be defaulted to 0, and need not be specified):
-+ NAME -- The name of this option's long option (may be zero)
-+ KEY -- The KEY to pass to the PARSER function when parsing this option,
-+ *and* the name of this option's short option, if it is a
-+ printable ascii character
-+ ARG -- The name of this option's argument, if any
-+ FLAGS -- Flags describing this option; some of them are:
-+ OPTION_ARG_OPTIONAL -- The argument to this option is optional
-+ OPTION_ALIAS -- This option is an alias for the
-+ previous option
-+ OPTION_HIDDEN -- Don't show this option in --help output
-+ DOC -- A documentation string for this option, shown in --help output
-+
-+ An options vector should be terminated by an option with all fields zero. */

-+ ARGP_KEY_NO_ARGS, which is only given if no non-option
-+ arguments were supplied to the program.
-+
-+ For structuring the help output, two features are used,
-+ *headers* which are entries in the options vector with the
-+ first four fields being zero, and a two part documentation
-+ string (in the variable DOC), which allows documentation both
-+ before and after the options; the two parts of DOC are
-+ separated by a vertical-tab character ('\v', or '\013'). By
-+ convention, the documentation before the options is just a
-+ short string saying what the program does, and that afterwards
-+ is longer, describing the behavior in more detail. All
-+ documentation strings are automatically filled for output,
-+ although newlines may be included to force a line break at a
