       parl - Binary PAR Loader

       (Please see pp for convenient ways to make self-contained executables,
       scripts or PAR archives from perl programs.)

       To make a PAR distribution from a CPAN module distribution:

	   % parl -p		     # make a PAR dist under the current path
	   % parl -p Foo-0.01	     # assume unpacked CPAN dist in Foo-0.01/

       To manipulate a PAR distribution:

	   % parl -i Foo-0.01-i386-freebsd-5.8.0.par   # install
	   % parl -i	       # auto-appends archname + perlver
	   % parl -i cpan://AUTRIJUS/PAR-0.74	       # uses CPAN author directory
	   % parl -u Foo-0.01-i386-freebsd-5.8.0.par   # uninstall
	   % parl -s Foo-0.01-i386-freebsd-5.8.0.par   # sign
	   % parl -v Foo-0.01-i386-freebsd-5.8.0.par   # verify

       To use from ./foo.par:

	   % parl -A./foo.par -MHello
	   % parl -A./foo -MHello      # the .par part is optional

       Same thing, but search foo.par in the @INC;

	   % parl -Ifoo.par -MHello
	   % parl -Ifoo	-MHello	       # ditto

       Run or script/ from foo.par:

	   % parl foo.par      # looks for '' by	default,
				       # otherwise run ''

       To make a self-containing executable containing a PAR file :

	   % parl -O./foo foo.par
	   % ./foo	       # same as above

       To embed	the necessary non-core modules and shared objects for PAR's
       execution (like "Zlib", "IO", "Cwd", etc), use the -b flag:

	   % parl -b -O./foo foo.par
	   % ./foo	       # runs anywhere with core modules installed

       If you also wish	to embed core modules along, use the -B	flag instead:

	   % parl -B -O./foo foo.par
	   % ./foo	       # runs anywhere with the	perl interpreter

       This is particularly useful when	making stand-alone binary executables;
       see pp for details.

       This stand-alone	command	offers roughly the same	feature	as "perl
       -MPAR", except that it takes the	pre-loaded .par	files via "-Afoo.par"
       instead of "-MPAR=foo.par".

       Additionally, it	lets you convert a CPAN	distribution to	a PAR
       distribution, as	well as	manipulate such	distributions.	For more
       information about PAR distributions, see	PAR::Dist.

       You can use it to run .par files:

	   # runs script/	in archive, uses its lib/* as libraries
	   % parl myapp.par     # runs or	script/ in myapp.par
	   % parl	       # also runs normal perl scripts

       However,	if the .par archive contains either or script/,
       it is used instead:

	   % parl myapp.par     # runs, with '' as	@ARGV

       Finally,	the "-O" option	makes a	stand-alone binary executable from a
       PAR file:

	   % parl -B -Omyapp myapp.par
	   % ./myapp		       # run it	anywhere without perl binaries

       With the	"--par-options"	flag, generated	binaries can act as "parl" to
       pack new	binaries:

	   % ./myapp --par-options -Omyap2 myapp.par   # identical to ./myapp
	   % ./myapp --par-options -Omyap3 myap3.par   # now with different PAR
