-== NAME
-
-nng_opts_parse - parse command line options
-
-== SYNOPSIS
-
-[source, c]
-----
-#include <nng/nng.h>
-#include <nng/supplemental/util/options.h>
-
-typedef struct nng_optspec {
-    const char *o_name;  // Long style name (may be NULL for short only)
-    int         o_short; // Short option (no clustering!)
-    int         o_val;   // Value stored on a good parse (>0)
-    bool        o_arg;   // Option takes an argument if true
-} nng_optspec;
-
-int nng_opts_parse(int argc, char *const *argv, const nng_optspec *spec, int *val, char **arg, int *idx);
-----
-
-== DESCRIPTION
-
-The `nng_opts_parse()` is function is a supplemental function intended to
-facilitate parsing command line arguments.
-This function exists largely to stand in for `getopt()` from POSIX
-systems, but it is available everywhere that _NNG_ is, and it includes
-some capabilities missing from `getopt()`.
-
-The function parses arguments from `main()` (using _argc_ and _argv_),
-starting at the index referenced by _idx_.
-(New invocations typically set the value pointed to by _idx_ to 1.)
-
-Options are parsed as specified by _spec_ (see <<Option Specification>>.)
-The value of the parsed option will be stored at the address indicated by
-_val_, and the value of _idx_ will be incremented to reflect the next
-option to parse.
-
-TIP: For using this to parse command-line like strings that do not include
-the command name itself, set the value referenced by _idx_ to zero
-instead of one.
-
-If the option had an argument, a pointer to that is returned at the address
-referenced by _arg_.
-
-This function should be called repeatedly, until it returns either -1
-(indicating the end of options is reached) or a non-zero error code is
-returned.
-
-=== Option Specification
-
-The calling program must first create an array of `nng_optspec` structures
-describing the options to be supported.
-This structure has the following members:
-
-`o_name`::
-
-  The long style name for the option, such as "verbose".
-  This will be parsed on the command line when it is prefixed with two dashes.
-  It may be `NULL` if only a short option is to be supported.
-
-`o_short`::
-
-  This is a single letter (at present only ASCII letters are supported).
-  These options appear as just a single letter, and are prefixed with a single dash on the command line.
-  The use of a slash in lieu of the dash is _not_ supported, in order to avoid confusion with path name arguments.
-  This value may be set to 0 if no short option is needed.
-
-`o_val`::
-
-  This is a numeric value that is unique to this option.
-  This value is assigned by the application program, and must be non-zero
-  for a valid option.
-  If this is zero, then it indicates the end of the specifications, and the
-  rest of this structure is ignored.
-  The value will be returned to the caller in _val_ by `nng_opts_parse()` when
-  this option is parsed from the command line.
-
-`o_arg`::
-
-  This value should be set to `true` if the option should take an argument.
-
-=== Long Options
-
-Long options are parsed from the _argv_ array, and are indicated when
-the element being scanned starts with two dashes.
-For example, the "verbose" option would be specified as `--verbose` on
-the command line.
-If a long option takes an argument, it can either immediately follow
-the option as the next element in _argv_, or it can be appended to
-the option, separated from the option by an equals sign (`=`) or a
-colon (`:`).
-
-=== Short Options
-
-Short options appear by themselves in an _argv_ element, prefixed by a
-dash (`-`).
-If the short option takes an argument, it can either be appended in the
-same element of _argv_, or may appear in the next _argv_ element.
-
-NOTE: Option clustering, where multiple options can be crammed together in
-a single _argv_ element, is not supported by this function (yet).
-
-=== Prefix Matching
-
-When using long options, the parser will match if it is equal to a prefix
-of the `o_name` member of a option specification, provided that it do so
-unambiguously (meaning it must not match any other option specification.)
-
-== EXAMPLE
-
-The following program fragment demonstrates this function.
-
-[source, c]
-----
-    enum { OPT_LOGFILE, OPT_VERBOSE };
-    char *logfile; // options to be set
-    bool verbose;
-
-    static nng_optspec specs[] = {
-        {
-            .o_name = "logfile",
-            .o_short = 'D',
-            .o_val = OPT_LOGFILE,
-            .o_arg = true,
-        }, {
-            .o_name = "verbose",
-            .o_short = 'V',
-            .o_val = OPT_VERBOSE,
-            .o_arg = false,
-        }, {
-            .o_val = 0; // Terminate array
-        }
-    };
-
-    for (int idx = 1;;) {
-        int rv, opt;
-        char *arg;
-        rv = nng_opts_parse(argc, argv, specs, &opt, &arg, &idx);
-        if (rv != 0) {
-            break;
-        }
-        switch (opt) {
-        case OPT_LOGFILE:
-            logfile = arg;
-            break;
-        case OPT_VERBOSE:
-            verbose = true;
-            break;
-        }
-    }
-    if (rv != -1) {
-        printf("Options error: %s\n", nng_strerror(rv));
-        exit(1);
-    }
-----
-
-== RETURN VALUES
-
-This function returns 0 if an option parsed correctly, -1 if
-no more options are available to be parsed, or an error number otherwise.
-
-== ERRORS
-
-[horizontal]
-`NNG_EAMBIGUOUS`:: Parsed option matches more than one specification.
-`NNG_ENOARG`:: Option requires an argument, but one is not present.
-`NNG_EINVAL`:: An invalid (unknown) argument is present.
