Hi Gerd,
what does "to hide the perl script" mean?

BTW, the preferred shebang line (in ctan-o-mat.pl) is

  #!/usr/bin/env perl

This allows that Perl is found in PATH.  Some users might have a newer
version of Perl in /usr/local/bin.

The wrapper script (ctan-o-mat) isn't needed.  If properly installed,
TeX Live creates symlinks to *.pl files in bin/<platform> directories
for all Unix systems and a runscript wrapper in bin/win32 which also
makes the Perl shipped with TeX Live visible to the script.

All you have to do is to provide the .pl file.

For more info about the wrapper for Windows, see the comments in

  http://tug.org/svn/texlive/trunk/Master/bin/win32/runscript.tlu

Please note that the Perl for Windows shipped with TL doesn't contain
all the packages available from CPAN.  It's advisable to test the
script on Windows.

Regards,
  Reinhard
