SYNOPSIS

        my $parser = MeSH::Parser::ASCII->new( meshfile => 'd2010.bin' );
        
        # parse the file
        $parser->parse();
        
        # loop through all the headings
        while ( my ( $id, $heading ) = each %{ $parser->heading } ) {

DESCRIPTION

Parser for the MeSH ASCII format.

meshfile

MeSH file in ASCII format

METHODS

parse()

heading

Returns a hash ref collection of all the parsed headings. Each consists of a label, and id and synonyms if any were available.
