Actually, I forgot another way. This is the install script for Magma:



SMSqueakMap default loadUpdates.

(Smalltalk hasClassNamed: #MaObjectRepository)
     ifFalse: [ SMSqueakMap default installPackageNamed: 'Magma' 
version: '1.3 server' ].

#('Magma-Tester-cmm.395' 'Magma-Squeak-Tester-cmm.2') do:
     [ : each | (Installer repository: 'http://www.squeaksource.com/Magma')
     install: each ]




That is short, doesn't list all packages individually, and installs lots 
and lots of packages. It comes as a downloadable script from here:

http://wiki.squeak.org/squeak/2657

Drop that on the World and step back, while it loads everything. This, 
also, could go in a script deployed by a button in SM.
