+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 is an interface for parsing unix-style argument vectors. Unlike
++ the common getopt interface, it provides many advanced features in
++ addition to parsing options, such as automatic output in response to
++ `--help' and `--version' options.
++ A library can export an argp option parser, which programs can easily
++ use in conjunction with their own option parser.
++ A new shared object "libuargp" is created. The "libc.so" linker script
++ contains the AS_NEEDED entry for getting the libuargp linked automatically.
++ Argp support is needed by elfutils libdw.
++
++ Most people can safely answer N.

++/* 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. */
