=head1 NAME

SQL::Translator::Parser::Sybase - parser for Sybase

=head1 SYNOPSIS

  use SQL::Translator::Parser::Sybase;

=head1 DESCRIPTION

Mostly parses the output of "dbschema.pl," a Perl script freely
available from http://www.midsomer.org.  The parsing is not complete,
however, and you would probably have much better luck using the
DBI-Sybase parser included with SQL::Translator.
