I've uploaded a version of ScriptManager that works in Squeak4.4-12327, to ss3 at <http://ss3.gemstone.com/ss/ScriptManager.html>.
It was forked from the one at <http://www.squeaksource.com/ScriptManager.html>around version 13 just before they switched to using Fuel for serialization. I added syntax highlighting for the workspaces.

Installer ss3
     project: 'ScriptManager';
     install: 'ScriptManager-Core-kgb.14';
     install: 'ScriptManager-Help-kgb.2'.

ScriptManager open.

I would like to add this to SqueakMap if someone could quickstep me through the process.

Thx,
Ken G. Brown
