[Glass] Metacello docs and version to use

[Iwan Vosloo via Glass]

Hi there.

I have some questions about Metacello ...

I am trying to load a few projects into a fresh GemStone 3.4 (the 
shipped seaside extent) using the Metacello scripting API.

I follow the docs for Metacello here: 
https://github.com/Metacello/metacello/blob/v1.0.0-beta.32.18/docs/MetacelloScriptingAPI.md

Are those the correct docs to follow, given the version of Metacello in 
GS 3.4?

I've checked with:

   (Metacello image
     configuration: [:spec | true ];
     list) collect: [ :p| p version printString ]

Which gives amongst others:

   >=1.0-beta.32 [ConfigurationOfMetacello]

Partly why I wonder is that if I do, eg:

   Metacello new
     configuration: 'Magritte3';
     version: '3.5.1';
     repository: 'http://smalltalkhub.com/mc/Magritte/Magritte3/main/';
     onConflictUseIncoming: #('BaselineOfGrease') useLoaded: #();
     load.

...it complains that a Metacello doesNotUnderstand 
#onConflictUseIncoming:useLoaded:

I then check:

  Metacello  allSelectors select: [:s| s beginsWith: 'onConflict' ]

and only get: onConflict:

Am I using the correct docs?
Can I assume Metacello in the shipped GemStone 3.4 seaside image is 
up-to-date?

I notice in those docs that: "Currently Pharo-1.3, Pharo-1.4, Pharo-2.0, 
and Squeak4.3 are supported."

.... does that mean Gemstone is not?

Regards
Iwan
