Is it right that all of the .cls files contain the macro for "document class?"

(The meaning of this English sentence is a bit hard to understand...) If you would like to learn something about classes, have a look at the clsguide on CTAN or type texdoc clsguide at the command prompt.

Anyway, you have answered my question even though I did not express myself thoroughly. Thanks.
