+ *
+ * More than one such match may occur, in which case the action for

+ *
+ * There are three possible actions in case of a match:
+ *
+ * i) An integer (int or unsigned) variable determined by 'offset' is
+ *    set to 'value'
+ *
+ * ii) The processing function is called, with 'value' as the key
+ *
+ * iii) An integer (any) or string (char *) variable determined by
+ *    'offset' is set to the value of an option parameter
+ *
+ * 'offset' should normally be either set to
+ *
+ *  - 'offsetof(struct foo, member)'  actions i) and iii)
+ *
+ *  - -1			      action ii)
+ *
+ * The 'offsetof()' macro is defined in the <stddef.h> header.
+ *
+ * The template determines which options match, and also have an
+ * effect on the action.  Normally the action is either i) or ii), but
+ * if a format is present in the template, then action iii) is
+ * performed.
+ *
+ * The types of templates are:
+ *
+ * 1) "-x", "-foo", "--foo", "--foo-bar", etc.	These match only
+ *   themselves.  Invalid values are "--" and anything beginning
+ *   with "-o"
+ *
+ * 2) "foo", "foo-bar", etc.  These match "-ofoo", "-ofoo-bar" or
+ *    the relevant option in a comma separated option list
+ *
+ * 3) "bar=", "--foo=", etc.  These are variations of 1) and 2)
+ *    which have a parameter
+ *
+ * 4) "bar=%s", "--foo=%lu", etc.  Same matching as above but perform
+ *    action iii).
+ *
+ * 5) "-x ", etc.  Matches either "-xparam" or "-x param" as
+ *    two separate arguments
+ *
+ * 6) "-x %s", etc.  Combination of 4) and 5)
+ *
