%
%  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.

%     if \NAME is definable

%            \NAME == \@rmk{NAME}{TEXT}
%            \endNAME == \@endremark

%            \endNAME == \@endremark
%       else  error
