- % * REMARK ENVIRONMENTS *
- % ****************************************
- %
- % The user creates his own remark-like environments with the command
- % \newremark{NAME}{TEXT}[COUNTER] or
- % \newremark{NAME}[OLDNAME]{TEXT}
- % This defines the environment NAME to be just as one would expect a
- % remark environment to be, except that it prints ``TEXT'' instead of
- % ``Remark''.
- %
- % If OLDNAME is given, then environments NAME and OLDNAME use the same
- % counter, so using a NAME environment advances the number of the next
- % NAME environment, and vice-versa.
- %
- % If COUNTER is given, then environment NAME is numbered within COUNTER.
- % E.g., if COUNTER = subsection, then the first NAME in subsection 7.2
- % is numbered TEXT 7.2.1.
- %
- % The way NAME environments are numbered can be changed by redefining
- % \theNAME.
- %
- % DOCUMENT STYLE PARAMETERS
- %
- % \@rmkcounter{COUNTER} : A command such that
- % \edef\theCOUNTER{\@rmkcounter{COUNTER}}
- % defines \theCOUNTER to produce a number for a remark environment.
- % The default is:
- % BEGIN \noexpand\arabic{COUNTER} END
- %
- % \@rmkcountersep : A separator placed between a remark number and
- % the number of the counter within which it is numbered.
- % E.g., to make the third remark of section 7.2 be numbered
- % 7.2-3, \@rmkcountersep should be \def'ed to '-'. Its
- % default is '.'.
- %
- % \@beginremark{NAME}{NUMBER} : A command that begins a remark
- % environment for a 'remark' named 'NAME NUMBER' --
- % e.g., \@beginremark{Lemma}{3.7} starts Lemma 3.7.
- %
- % \@opargbeginremark{NAME}{NUMBER}{OPARG} : A command that begins a remark
- % environment for a 'remark' named 'NAME NUMBER' with optional
- % argument OPARG -- e.g., \@beginremark{Lemma}{3.7}{Jones}
- % starts `Lemma 3.7 (Jones):'.
- %
- % \@endremark : A command that ends a remark environment.
