libargtable2-0 binary package in Ubuntu Focal s390x

 Argtable is an ANSI C library for parsing GNU style command line arguments.
 It enables a program's command line syntax to be defined in the source code as
 an array of argtable structs. The command line is then parsed according to that
 specification and the resulting values are returned in those same structs where
 they are accessible to the main program. Both tagged (-v, --verbose, --foo=bar)
 and untagged arguments are supported, as are multiple instances of each
 argument. Syntax error handling is automatic and the library also provides the
 means for displaying the command line syntax directly from the array of
 argument specifications.
 .
 argtable can function as a "getopt_long" replacement, without the user of the
 program noticing the difference. Unlike "getopt_long", however, argtable is
 cross platform, working on all Posix systems, as well as Windows and Mac.
