I've stumpled over this answer to another problem, and it states:
The
articleclass recognises thetitlepageoption, which forces the\maketitlecommand to create a separate page.
To me the wording of this sentence implies that there possibly may be document classes which do not recognise the titlepage option. Hence my question is:
Which core document classes support the titlepage option and which do not?
(And for those classes that do not support this option: Which of them put the title on a separate page by default?)
titlepageamong the options set via the\documentclass[...]{<name of class>}instruction. If LaTeX issues a warning that the optiontitlepagewasn't used, bingo!, you know it's not set up to use this option. Of course, (almost) anyone can set up a document class and set up an option calledtitlepage. The crux is, what does the document class do if this option is set? – Mico Nov 29 '16 at 20:42
