The size of this fee is to be determined, in each instance, %% by the commercial user, depending on his/her judgment of the value of %% bidi for his/her product. %% %% %% The conditions for this are as follows: %% %% The producer of a proprietary and commercially market product %% that involves typesetting using bidi is asked to determine %% the value of a license fee for using bidi if %% %% - the product is a document and the producer has decided to %% include bidi to typeset (parts of) the document or has %% directed the author of the document to include bidi (for %% example, by providing a class file to be used by the author) %% %% - the product is a LaTeX class or package that includes bidi %% %% %% There is no moral obligation in case %% %% - the product is a document but producer has not directed %% the author to include bidi (in that case the moral obligation %% lies with the author of the document) %% %% - the product does not involve typesetting, e.g., consists, for %% example, of distributing bidi and its documentation. %% %% - the product is not proprietary, i.e., is made available as free %% software itself (which doesn't prohibit its commercial marketing) %% %% - bidi is used for non-commercial purposes %% %% %% Determinating a license fee might result in a license fee of zero %% (i.e., no payment) in case a producer has determined that the use %% of bidi has no enhancing effect on the product. This is a %% plausible scenario, i.e., in the above two cases the producer is %% only asked to evaluate the value of bidi for the product %% not for the payment of a license fee per se (which might or might %% not follow from this evaluation). %% %% The license fee, if any, can be payed to the author of %% the program who can be contacted at %% %% vafakhlgh@gmail.com %% %% %% %% %% End of file `breqn-xetex-bidi.def'.
