=head1 NAME

ppidump - Dump Perl code as PPI structure.

=head1 SYNOPSIS

  ppidump                     #Read from STDIN
  ppidump MyModule.pm         #Read code from file
  ppidump 'my $foo = $bar;'   #Read code as from string
  ppidump -w 'foo( );'        #Show whitespace tokens

=head1 DESCRIPTION

This is a simple tool for helping to develop Perl::Critic::Policy
modules.  If you want to see how L<PPI|PPI> would parse a snippet of
code, just feed it to C<ppidump>.

By default, whitespace tokens are hidden.  Use the C<-w> flag to show
them.
