=head1 NAME

runperl.bat - "universal" batch file to run perl scripts

=head1 SYNOPSIS

	C:\> copy runperl.bat foo.bat

	C:\> foo

	[..runs the perl script `foo'..]

	C:\> foo.bat

	[..runs the perl script `foo'..]

=head1 DESCRIPTION

This file can be copied to any file name ending in the ".bat" suffix.

When executed on a DOS-like operating system, it will invoke the perl

script of the same name, but without the ".bat" suffix.  It will

look for the script in the same directory as itself, and then in

the current directory, and then search the directories in your PATH.

It relies on the C<exec()> operator, so you will need to make sure

that works in your perl.

This method of invoking perl scripts has some advantages over

batch-file wrappers like C<pl2bat.bat>:  it avoids duplication

of all the code; it ensures C<$0> contains the same name as the

executing file, without any egregious ".bat" suffix; it allows

you to separate your perl scripts from the wrapper used to

run them; since the wrapper is generic, you can use symbolic

links to simply link to C<runperl.bat>, if you are serving your

files on a filesystem that supports that.

On the other hand, if the batch file is invoked with the ".bat"

suffix, it does an extra C<exec()>.  This may be a performance

issue.  You can avoid this by running it without specifying

the ".bat" suffix.

Perl is invoked with the -x flag, so the script must contain

a C<#!perl> line.  Any flags found on that line will be honored.

=head1 BUGS

Perl is invoked with the -S flag, so it will search the PATH to find

the script.  This may have undesirable effects.
