The closurebuilder tool has its doc here:
The section "Resolving Closure Library Dependencies" shows how to create a sequentially correct .js file list but isn't very explicit about how to use the list.
I think I have resolved this but am noting my solution here for feedback. It would probably be nice to have more explicit guidance in the documentation as well, for the other beginners out there :).
The solution seems to be to just enclose all the resulting .js files into script tags and add them to the html file...
Also, maybe it's worthwhile mentioning that I was initially puzzled by a strange error:
TypeError: childCtor is undefined
TypeError: this.stopEvent is not a function
(field.js line 136)
It turned out this was due to a
goog.inherits(value_with_a_typo, goog.editor.SeamlessField);
statement... also noting this here in case anyone else out there googles this error and needs the needle from the haystack.
