+=head1 NAME
+
+pl2bat - wrap perl code into a batch file
+
+=head1 SYNOPSIS
+
+B<pl2bat> [B<-h>] S<[B<-a> I<argstring>]> S<[B<-s> I<stripsuffix>]> [files]
+
+=head1 DESCRIPTION
+
+This utility converts a perl script into a batch file that can be
+executed on DOS-like operating systems.
+
+Note that by default, the ".pl" suffix will be stripped before adding
+a ".bat" suffix to the supplied file names.  This can be controlled
+with the C<-s> option.
+
+The default behavior on WindowsNT is to generate a batch file that
+uses the C<%*> construct to refer to all the command line arguments
+that were given to it, so you'll need to make sure that works on your
+variant of the command shell.  It is known to work in the cmd.exe shell
+under WindowsNT.  4DOS/NT users will want to put a C<ParameterChar = *>
+line in their initialization file, or execute C<setdos /p*> in
+the shell startup file.  On Windows95 and other platforms a nine
+argument limit is imposed on command-line arguments given to the
+generated batch file, since they may not support C<%*> in batch files.
+This can be overridden using the C<-a> option.
+
+=head1 OPTIONS
+
+=over 8
+
+=item B<-a> I<argstring>
+
+Arguments to invoke perl with in generated batch file.  Defaults to
+S<"-x -S %0 %*"> on WindowsNT, S<"-x -S %0 %1 %2 %3 %4 %5 %6 %7 %8 %9">
+on other platforms.
+
+=item B<-s> I<stripsuffix>
+
+Strip a suffix string from file name before appending a ".bat"
+suffix.  The suffix is not case-sensitive.  It can be a regex if it
+begins with `/' (the trailing '/' being optional.  Defaults to ".pl".
+
+=item B<-h>
+
+Show command line usage.

+
+=head1 EXAMPLES
+
+	C:\> pl2bat foo.pl bar.PM 
+	[..creates foo.bat, bar.PM.bat..]
+	
+	C:\> pl2bat -s "/\.pl|\.pm/" foo.pl bar.PM
+	[..creates foo.bat, bar.bat..]
+	
+	C:\> pl2bat < somefile > another.bat
+	
+	C:\> pl2bat > another.bat
+	print scalar reverse "rekcah lrep rehtona tsuj\n";
+	^Z
+	[..another.bat is now a certified japh application..]
+
+=head1 BUGS
+
+C<$0> will contain the full name, including the ".bat" suffix
+when the generated batch file runs.  If you don't like this,
+see runperl.bat for an alternative way to invoke perl scripts.
+
+Default behavior is to invoke Perl with the -S flag, so Perl will
+search the PATH to find the script.  This may have undesirable
+effects.
