The main goal is +to let you reprint theorems in the appendix with their proofs, so the +text isn't cluttered with long proofs, but the reader doesn't have to +keep flipping back to the text to find out what you're talking about in +the appendix. + +It also has the side benefits that the syntax here involves less typing +and fewer redundancies than the default, so I use it even for things +that won't ever be proven.

The format here is: +\newtype{nickname}{numbered like}{title} + +E.g., the second line lets me put + \stmt{thrm}{mortalityresult}{Socrates is mortal.} +in the tex file, since it defined the nickname `thrm'. If the statement +counter is up to #7, then the output will be: + Theorem 7: Socrates is mortal. +since thrms use the statement counter and print `Theorem'. To refer to +this theorem in the text, you have two choices: + \refstmt{mortalityresult} ===> Theorem 7 + Theorem \ref{mortalityresult} ===> Theorem 7 +The first form is nice because after you prove your result, you can +change it from a theorem to a conjecture without hunting through the +text to fix every reference. + +You can see that all of the results use the `statement' counter and +all of the inputs use the `ass' counter. Proposition 1 may be followed +by Theorem 2, followed by Corollary 3. This is my preferred numbering +scheme, suggested by Paolo Ghirardato. After all, the intent of numbering +these things is not to keep score as to how many theorems you've got, +but to make it easy for the reader to find what you're referring to; +a consistent numbering system facilitates this (especially in a long proof +appendix). + +[On the other hand, a referee of one of my papers complained that +17 theorems and 18 corollaries was too many, and I could cut that in +half. Of course, there were only 18 results total, and s/he was only +glancing at the two results on the last page.] + +To use independent numbering for each type, simply change the second field +in the definitions above to match the first field in each case.
