Parrot::Configure::Options - Process command-line options to Configure.pl
use Parrot::Configure::Options qw( process_options ); $args = process_options( { mode => q{configure}, } );
Parrot::Configure::Options exports on demand the subroutine process_options(), which processes the command-line options provided to Configure.pl.
process_options()
If you provide Configure.pl with either --help or --version, process_options() will print out the appropriate message and perform a bare return, i.e., the return value will be undef. The calling script -- whether Configure.pl or a test file -- can then check for the definedness of process_options()'s return value and proceed appropriately.
--help
--version
return
undef
An array of valid command-line option names stored internally is consulted; the program will die if an invalid option is called.
Purpose
Process command-line options provided to Configure.pl and proceed appropriately.
Arguments

argv : reference to @ARGV; defaults to [] script : Perl's $0: the calling program; defaults to 'Configure.pl' parrot_version : string holding Parrot version number (currently supplied by Parrot::BuildUtil::parrot_version()) svnid : string holding Subversion Id string
Return Value

Bare return (undef).
All other options
Reference to a hash of option names and values.
