       __numset - deals with number-sets
       This program is part of afbackup


       __numset <set-1-specifier> { + | - | in} <set-2-specifier>


       This  Program  deals with set of numbers and can either remove elements
       of one set that exists in another set, or merge two sets.

       If the second argument is a +, then the two sets are  merged.   If  the
       second argument is -, the elements in set2 are removed from set1.

       If  the  second  argument  is the word "in", then it is tested, whether
       elements of set 1 are also contained in set 2.

       The number of common elements will be the result in that case.

       If the first argument is the character #  (must  be  escaped  in  shell
       scripts,  e.g.  write ’#’), the result is the number of elements in the
       set given as second argument.  Number set specifiers should not contain
       whitespace and may consist of numbers, commas and dashes.


       Examples how to use __numset and the results:

       prompt# __numset 1-3,5-9,14 + 10-12

              The output will be:


       prompt# __numset 1-3,5-9,14 - 5-13

              The output will be:


       prompt# __numset 3 - ""

              The output will be:


       In this cases, it gives no output
              prompt# __numset "" - 4,6,8

              prompt# __numset 3 - 3-5

              prompt# __numset # 4-9
