Inclusion of Helper parts in the Official LDraw Parts Library

[Magnus Forsberg]

Helper Category

Not needed. From the !CATEGORY and !KEYWORDS spec: If a part has no !CATEGORY meta-statement, the category is assumed to be the first word in the part name (ie. the first word of the first line of the part file).

I don't question this decision, but I don't understand this bit. Maybe it could be explained?

I'm thinking like this:
Why do we have a list of categories? - It is to be able to sort all descriptions that do not start with a specific word.
Which words are specific? - The words that are in the list of categories.
Doesn't that mean that if the first word is not in the list of categories, a category from the list must be selected?
The word Helper is not included in the list of categories.
