You can get more information by sending e-mail to elisabete@max.acs.washington.edu. Reason #452 for ordering the tape rather than FTPing: Elisabeth Tachikawa can answer questions about any problems you encounter installing the tape (including such things as "why isn't the online display support working on my DECstatio?" etc.) >Also, I do not understand the implications of the new virtual font >convention. Does there exist somewhere an explanation of what virtual >fonts are, and what practical changes must be made to accommodate them? >Are TFM and PK formats obsolete or intermediate now? Reason #23 for joing TUG: You receive TUGboat which contains many informative articles on TeX and related software. TUGboat 11#1 contained an article by Donald Knuth explaining the point behind virtual fonts. Since you doubtless don't have a copy, I'll summarize. (1) VF allows one to make "composite fonts" where a single TeX character can represent any sequence of DVI commands. Thus, it is possible to do things like (a) remap the coding of a font, (b) construct accented characters from a character and accent or (c) almost anything else one can imagine. (2) To use the VF features, you need to have a driver that knows about virtual fonts. As far as I know only Tom Rokicki's dvips 5.x and the ArborText drivers can handle this at present (can anybody name others?). In the near future, a program DVIcopy will be released which will convert a DVI file referencing VF fonts to a VF-free DVI file. -dh The TeX Users Group can be reached at: TeX Users Group P.O.
