The documentation is in the module file.  Once you install
the file, you can read it with perldoc.

	perldoc Business::ISSN

If you want to read it before you install it, you can use
perldoc directly on the module file.

	perldoc  lib/ISSN.pm

This module is also in CVS on SourceForge

Business::ISSN - Perl extension for International Standard Serial Numbers

=head1 SYNOPSIS

	use Business::ISSN;
	$issn_object = Business::ISSN->new('1456-5935');

	$issn_object = Business::ISSN->new('14565935');

	# print the ISSN (with hyphen)
	print $issn_object->as_string;

	# check to see if the ISSN is valid
	$issn_object->is_valid;

	#fix the ISSN checksum.  BEWARE:  the error might not be
	#in the checksum!
	$issn_object->fix_checksum;

	#EXPORTABLE FUNCTIONS

	use Business::ISSN qw( is_valid_checksum );

	#verify the checksum
	if( is_valid_checksum('01234567') ) { ... }

=head1 DESCRIPTION

=over 4

=item new($issn)

The constructor accepts a scalar representing the ISSN.

The string representing the ISSN may contain characters
other than [0-9xX], although these will be removed in the
internal representation.  The resulting string must look
like an ISSN - the first seven characters must be digits and
the eighth character must be a digit, 'x', or 'X'.

The string passed as the ISSN need not be a valid ISSN as
long as it superficially looks like one.  This allows one to
use the C<fix_checksum> method. 

One should check the validity of the ISSN with C<is_valid()>
rather than relying on the return value of the constructor. 

If all one wants to do is check the validity of an ISSN, 
one can skip the object-oriented  interface and use the
c<is_valid_checksum()> function which is exportable on demand.

If the constructor decides it can't create an object, it
returns undef.  It may do this if the string passed as the
ISSN can't be munged to the internal format.

=item $obj->checksum

Return the ISSN checksum.

=item $obj->as_string

Return the ISSN as a string. 

A terminating 'x' is changed to 'X'.

=item  $obj->is_valid

Returns 1 if the checksum is valid.

Returns 0 if the ISSN does not pass the checksum test.  
The constructor accepts invalid ISSN's so that
they might be fixed with C<fix_checksum>.  

=item  $obj->fix_checksum

Replace the eighth character with the checksum the
corresponds to the previous seven digits.  This does not
guarantee that the ISSN corresponds to the product one
thinks it does, or that the ISSN corresponds to any product
at all.  It only produces a string that passes the checksum
routine.  If the ISSN passed to the constructor was invalid,
the error might have been in any of the other nine positions.

=back

=head2 EXPORTABLE FUNCTIONS

Some functions can be used without the object interface.  These
do not use object technology behind the scenes.

=over 4

=item is_valid_checksum('01234567')

Takes the ISSN string and runs it through the checksum
comparison routine.  Returns 1 if the ISSN is valid, 0 otherwise.
