Is it possible to install OpenCobalt into Squeak 5.2

Open Cobalt "http://opencobalt.org (Best to run this from an image in an open cobalt directory)"

Installer ss project: 'TweakCore'; install: 'update'.

[Installer ss project: 'TweakExtras'; install: 'update'] on: (Smalltalk at: #CUnsynchronizedModification) do: [:ex | ex resume].

Installer cobalt project: 'Tweak'; answer: 'Would you like to conserve memory at all costs?' with: true; answer: 'Password for interactive VNC connections?' with: 'cobalt'; answer: 'Would you like to add the RFBServer to the World open menu?' with: true; install: 'update'

I wonder what an open cobalt directory is.
