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 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: 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, 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. 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. + +=head1 SEE ALSO + +perl, perlwin32, pl2bat.bat + +=cut + + +__END__ +:endofperl
