** Using WeBWorK **

If you use

 BEGIN_HINT 

 hint material 

 END_HINT 

then TeX will be processed in the same way that it is with BEGIN_TEXT/END_TEXT.

(This is somewhat recent, since about version 2.3 of PG.)

BEGIN_HINT is translated into the following, uglier, construction which
could also be used:

HINT(EV3(<<'END_HINT'));

hint stuff

END_HINT
