This is about the perl package Catalyst. For information about catalysts as agents that lower the activation energy of a chemical reaction, see your chemistry or biophysics textbook.
perl -MCPAN -e shell >> install Catalyst::Runtime (hit return to take all defaults) (implies installation of around 100 dependencies) (may require fresh installation of Bundle::CPAN) (correctly configured version running on bks150)
>> install Task::Catalyst (takes about an hour!)
