%		Macros For entering greek mode,
%		and delimiter preferences.
%		-------------------------------
%
%	\begingreek : Begin a group of Greek Text.
%	^^^^^^^^^^^^  Everything is enclosed in a group to keep
%	              changes local. Then we switch to greek hyphenation
%		      and iniciate the greekmode. This assigns the correct
%	              \catcode values to punctuation and accentuation marks.
%	              We then reload the information of the point
%	              size used last and switch to the family needed.
%	              The \t@f@nt and \t@f@m macro is used to ensure that 
%	              or fonts and families are remembered.
%
%	\endgreek :   Ends a group of Greek Text.
%	^^^^^^^^^^    Before ending the group we save information
%	              about the current font, to be used when we re-enter 
%	              greek mode.
%
%	\gr@@km@de :  Switches to greek interpretation of ascii characters
%	^^^^^^^^^^^   Normally changes are kept local but can be used
%	              as a general macro to obtain a global greek mode.
%	              Note the different use of | if this is chosen
%	              to be a delimiter.

%
%	It is very frequent that the user will ask to \end the document
%	before a greek group was closed. In order to prevent this we 
%	redefine the \end command after saving the old one in \@ldend.
%	The new \end checks for un-ended greek groups and if it is found
%	a warning message is issued and the group is automatically closed.

%
%	Since it is possible that switching from one language to

%	and \endgreek is defined. This is done through the definition of
%	delimiters; available delims are | and $. If \greekdelims{bar}
%	is chosen then a greek block is marked as | ..greek text.. |
%	In order to access |, use \|.
%	If $ is used, use \math for math mode and \math\math for
