You might have asked the question in reverse.For daily needs
and for normal development purposes in Perl, we need to use
many modules.

We will get the modules from a common repository called
"Cpan", in which programmers from all over the world keep
the modules. Anyone can use them.

Eg.,

Data::Dumper
CGI
HTML::Template
CGI::Carp qw(fatalsToBrowser);
CGI::Ajax ...
