+One of the frequent problems reported by new users of Catalyst is that
+it can be extremely time-consuming and difficult to install.

+One of the great strengths of Perl as a programming language is its use
+of CPAN, the Comprehensive Perl Archive Network, an enormous global
+repository containing over 10,000 free modules. For almost any basic
+task--and a very large number of non-basic ones--there is a module on
+CPAN that will help you. Catalyst has taken advantage of this, and uses
+a very large number of CPAN modules, rather than reinventing the wheel
+over and over again. On the one hand, Catalyst gains power and
+flexibility through this re-use of existing code. On the other hand,
+Catalyst's reliance on CPAN can complicate initial installations,
+especially in shared-hosting environments where you, the user, do not
+have easy control over what versions of other modules are installed.

+Fortunately, there are a growing number of methods that can dramatically
+ease this undertaking. Note that for many of these, you will probably
+need to install additional Catalyst-related modules (especially plugins)
+to do the things you want. As of version 5.70, Catalyst has split into
+two packages, L<Catalyst::Runtime>, which includes the core elements
+necessary to deploy a Catalyst application, and L<Catalyst::Devel>,
+which includes the Helpers and other things necessary or useful for
+developing Catalyst applications. In a purely deployment environment
+you can omit L<Catalyst::Devel>.
