NAME
    Perlito5 - a Perl5 compiler

SYNOPSIS
        use Perlito5::Compiler;
        use Perlito5::Javascript2::Emitter;
        use Perlito5::Javascript2::Runtime;

        my $perl5_source = ' print "hello, World!\n" ';
        $Perlito5::PKG_NAME = 'main';
        $Perlito5::PROTO    = {};
        my $ast = Perlito5::Grammar::exp_stmts($perl5_source, 0);
        print Dumper $ast;
        my $js_source = Perlito5::AST::CompUnit::emit_javascript2_program([
            Perlito5::AST::CompUnit->new( name => 'main', body => Perlito5::Match::flat($ast) )
        ]);
        print $js_source;


        # in the command line:

        perlito5 --help

        perlito5 -Cjs program.pl

DESCRIPTION
    This program reads Perl5 source code and generates native code.

    The compiler options are available with the command:

        perlito5 -h

COOKBOOK
  Obtaining a "perlito5.js" script that executes in the "node.js" Javascript compiler
        # Step 1: use perlito5 to compile perlito5 to Javascript.
        perlito5 --bootstrapping -Cjs `which perlito5` > perlito5.js

        # Step 2: ensure that PERL5LIB points to the directory where Perlito5.pm is installed.
        echo $PERL5LIB

        # Step 3: set PERL5LIB if needed.
        perldoc -l Perlito5
           # /usr/local/lib/perl5/site_perl/5.20.1/Perlito5.pm
        export PERL5LIB=/usr/local/lib/perl5/site_perl/5.20.1

        # Step 4: install nodejs if needed.

        # Step 5: this should work now:
        nodejs perlito5.js -e ' print "hello, World!\n" '
            # hello, World!
