-projects.
-
The key concept of Catalyst is DRY (Don't Repeat Yourself).

+=head1 CASE SENSITIVITY
+
+By default Catalyst is not case sensitive, so C<MyApp::C::FOO::Bar> becomes
+C</foo/bar>.
+
+But you can activate case sensitivity with a config parameter.
+
+ MyApp->config->{case_sensitive} = 1;
+
=head1 LIMITATIONS
mod_perl2 support is considered experimental and may contain bugs.
