+1 from me too.
This looks like a light weight addition with benefit for anyone wanting to use Metacello, and no harm otherwise.
I have not tried unloading Metacello-Base, but it has no dependencies so it should not be a problem. There is an #unloadMetacello method in the base package that presumably performs as advertised.

+1 from me if it loads/unloads cleanly (i'm pretty sure it does, but it's always better to check it out).

I have a small 3 class package (Metacello-Base[1]) that I would hope could be included in the Squeak4.4 release.
Of the 3 classes, the Metacello class is a stub class for the Metacello Scripting Api[2], that will bootstrap Metacello _if_ you use the scripting api. I am promoting the scripting api as the cross platform way to use Metacello. Instead of seeing install scripts fly by that look like this:
Gofer new package: 'ConfigurationOfSeaside30'; squeaksource: 'MetacelloRepository'; load. ((Smalltalk at: #ConfigurationOfSeaside30) version: #stable) load.
(with the caveat that Installer should be used for Squeak)...the install scripts will look like this:
Metacello new configuration: 'Seaside30'; version: #stable; squeaksource: 'MetacelloRepository'; load.
The same script will "do the right thing" on all three supported platforms (Squeak, Pharo, GemStone), presuming that the class Metacello is present in the base images:)
I've recently released a preview version[4] and am actively collecting feedback. I would think that I can finalize the visible portion of the scripting api by September...
I've been ensuring that the metacello preview release is functional on Squeak all along and I am currently running CI builds against Squeak4.3 using travis ci[5]. Moving forward I would add Squeak4.4 to the list of platforms for CI and publish updates to the Metacello-Base pacakge as needed.
The class comments for each of the classes provides basic documentation for using Metacello so I think that Metacello-Base is a clean and small presence for Metacello and will enable the use of "cross-platform install scripts for Metacello."
Thanks,
Dale
