c) If the modified program normally reads commands interactively when
run, you must cause it, when started running for such interactive use
in the simplest and most usual way, to print or display an
announcement including an appropriate copyright notice and a notice
that there is no warranty (or else, saying that you provide a
warranty) and that users may redistribute the program under these

Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19xx name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the
appropriate parts of the General Public License. Of course, the
commands you use may be called something other than `show w' and `show
c'; they could even be mouse-clicks or menu items--whatever suits your
program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here a sample; alter the names:

Acme::CPANModules::ReadingFilesBackward - List of modules to read files
backward (in reverse)
VERSION
This document describes version 0.003 of
Acme::CPANModules::ReadingFilesBackward (from Perl distribution
Acme-CPANModules-ReadingFilesBackward), released on 2023-10-31.
DESCRIPTION
Probably the fastest way, if you are on a Unix system, is to use the tac
command, which can read a file line by line in reverse order, or
paragraph by paragraph, or character by character, or word by word, or
by a custom separator string or regular expression. Example for using it
from Perl:
open my $fh, "tac /etc/passwd |";
print while <$fh>;
Another convenient way is to use the Perl I/O layer PerlIO::reverse. It
only does line-by-line reversing, but you can use the regular Perl API.
You don't even have to "use" the module explicitly (but of course you
or Acme::CM::Get:
% perl -MAcme::CM::Get=ReadingFilesBackward -E'say $_->{module} for @{ $LIST->{entries} }' | cpanm -n
or directly:
% perl -MAcme::CPANModules::ReadingFilesBackward -E'say $_->{module} for @{ $Acme::CPANModules::ReadingFilesBackward::LIST->{entries} }' | cpanm -n
This Acme::CPANModules module also helps lcpan produce a more meaningful
result for "lcpan related-mods" command when it comes to finding related
modules for the modules listed in this Acme::CPANModules module. See
App::lcpan::Cmd::related_mods for more details on how "related modules"
are found.

Probably the fastest way, if you are on a Unix system, is to use the B<tac>
command, which can read a file line by line in reverse order, or paragraph by
paragraph, or character by character, or word by word, or by a custom separator
string or regular expression. Example for using it from Perl:
open my $fh, "tac /etc/passwd |";
print while <$fh>;
Another convenient way is to use the Perl I/O layer L<PerlIO::reverse>. It
only does line-by-line reversing, but you can use the regular Perl API. You
don't even have to C<use> the module explicitly (but of course you have to get it
