:signification
The special method "help" accepts two parameters. The first is a key
which will be put to the variable \help_subject within the help text,
and the second is the text of the link.
The "css" class of the link is <span class="tt wims_code_words">oef_specialhelp</span> and can be configured.
If the \special{help} is put into statement or feedback of an exercise,
the help will use popup mode, unlike the usual "help" link in the module.
All the help content should be put into the oef source. No facility is
planned for module-level help, as the principle is that the independency
of oef files should not be destroyed by helps. However, if you have
several exercises sharing the same help texts, you may consider using cpp.
