=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.
