=head1 NAME
Bio::MapIO::mapmaker - A Mapmaker Map reader
=head1 SYNOPSIS
# do not use this object directly it is accessed through the Bio::MapIO system
use Bio::MapIO;
my $mapio = Bio::MapIO->new(-format => "mapmaker",
-file => "mapfile.map");
while ( my $map = $mapio->next_map ) { # get each map
foreach my $marker ( $map->each_element ) {
# loop through the markers associated with the map
}
}
=head1 DESCRIPTION
This object contains code for parsing and processing Mapmaker output
and creating L<Bio::Map::MapI> objects from it.
=head1 FEEDBACK
=head2 Mailing Lists
User feedback is an integral part of the evolution of this and other
Bioperl modules. Send your comments and suggestions preferably to
the Bioperl mailing list. Your participation is much appreciated.

Title : next_map
Usage : my $map = $factory->next_map;
Function: Get one or more map objects from the Mapmaker input
Returns : Bio::Map::MapI
Args : none

# Mapmaker input can be free-form, like the result of a copy-paste
# from a terminal, with no particular format before or after the
# map data. The $in_map variable is a flag that's set to 1 when
# we're reading map data lines and set back to 0 when we're finished.
