Monticello, Metacello ... Metaceller

Metacello is a nice package management system for Monticello in Pharo.
There are already various configurations for well known packages available in the MetacelloRepository project.

With a pharo image installed Metacello can be used to load a specific (or the latest) versions of Seaside:

  Gofer new
squeaksource: 'MetacelloRepository';
package: 'ConfigurationOfSeaside30';

(Smalltalk at: #ConfigurationOfSeaside30) loadLatestVersion

Tudor Girba now created a basic version of a browser called "Metaceller" for managing Metacello configurations that are already loaded in the image. Read more here.

To load in Pharo evaluate:

 Gofer new 
squeaksource: 'glamoroust';
package: 'ConfigurationOfGlamoroust';
(Smalltalk at: #ConfigurationOfGlamoroust) perform: #loadDefault.

After loading you can open the tool using:
