+=head1 NAME
+
+B::Bytecode - Perl compiler's bytecode backend
+
+=head1 SYNOPSIS
+
+B<perl -MO=Bytecode>[B<,-H>][B<,-o>I<script.plc>] I<script.pl>
+
+=head1 DESCRIPTION
+
+Compiles a Perl script into a bytecode format that could be loaded
+later by the ByteLoader module and executed as a regular Perl script.
+
+=head1 EXAMPLE
+
+ $ perl -MO=Bytecode,-H,-ohi -e 'print "hi!\n"'
+ $ perl hi
+ hi!
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-b>
+
+Save all the BEGIN blocks. Normally only BEGIN blocks that C<require>
+other files (ex. C<use Foo;>) are saved.
+
+=item B<-H>
+
+prepend a C<use ByteLoader VERSION;> line to the produced bytecode.
+
+=item B<-k>
+
+keep the syntax tree - it is stripped by default.
+
+=item B<-o>I<outfile>
+
+put the bytecode in <outfile> instead of dumping it to STDOUT.
+
+=item B<-s>
+
+scan the script for C<# line ..> directives and for <goto LABEL>
+expressions. When gotos are found keep the syntax tree.
+
+=back
+
+=head1 KNOWN BUGS
+
+=over 4
+
+=item *
+
+C<BEGIN { goto A: while 1; A: }> won't even compile.
+
+=item *
+
+C<?...?> and C<reset> do not work as expected.
+
+=item *
+
+variables in C<(?{ ... })> constructs are not properly scoped.
+
+=item *
+
+scripts that use source filters will fail miserably.
+

+
+=head1 NOTICE
+
+There are also undocumented bugs and options.
+
+THIS CODE IS HIGHLY EXPERIMENTAL. USE AT YOUR OWN RISK.
