%description
Mod_perl incorporates a Perl interpreter into the Apache web server,
so that the Apache web server can directly execute Perl code.
Mod_perl links the Perl runtime library into the Apache web server and
provides an object-oriented Perl interface for Apache's C language
API.  The end result is a quicker CGI script turnaround process, since
no external Perl interpreter has to be started.

Install mod_perl if you're installing the Apache web server and you'd
like for it to directly incorporate a Perl interpreter.
