=head1 NAME

Liberty::Parser - Parser for Synopsys Liberty(.lib).

=head1 VERSION

Version 0.04

=head1 SYNOPSIS

  use Liberty::Parser;
  my $parser = new Liberty::Parser;
  my $library_group  = $parser->read_file("standard_cell.lib");

  my $lib_name = $parser->get_group_name($library_group);
  print "Library Name: $lib_name\n";
  print $parser->get_attr_with_value($library_group,"nom_temperature");

=head1 DESCRIPTION

Liberty::Parser is indeed a Perl wrapper for a Liberty Parser which is written in C from
Synopsys's Open Liberty Project.

Liberty::Parser harnesses Open Libety Project with Perl through the help of SWIG (www.swig.org)
and implemented many handy functions to make information extracting from Liberty can
be easily accomplished.

To get Liberty::Parser work, you have to download liberty_parse from Open Liberty Project.
Compile the C source into linked library then put the linked library at somewhere it can
be found through the environment variable LD_LIBRARY_PATH. Please follow the guide in the
INSTALLATION section of README.
