I have +included everything but cmff10 cmfi10 cmfib10 and cminch. You have to +draw the line somewhere. + +No information that can be preserved is discarded. I have invented names +for fontdimens that afm does not know about. It is not likely that these +afms will be used anywhere where that would cause trouble, and maybe the +extra \fontdimens can teach by example. Otherwise the files are as close +to Adobe conventions as possible. If any character has a name in +the "Blue Book" that name is used, even when it differs from the +METAFONT name. + +If you are wondering why Computer Modern afms should exist at all, +think of Alan Jeffrey's fontinst, and the manipulations it permits. I +have my own set of awk and sed scripts that do much the same. PL +format contains more information than can be effectively stored in afm +format, but it is diffuse and difficult to read and edit. One of the +most interesting applications for Computer Modern afms is to build up +virtual fonts using the basic CM fonts as the raw fonts. You can get +almost, though not quite all, of DC encoding that way. With the +addition of a few specially designed characters you can get all of DC +encoding at a much cheaper price in font storage than is entailed in +making up entirely separate DC fonts. Besides that, you eliminate the +risk of creating dialect forms of Computer Modern characters. + +For further information on gf2afm, a conversion system using +Bourne Shell, Awk and Sed scripts which was used to produce +these afm files, write to: + +mackay@cs.washington.edu Pierre A.
