In order to use mwdvi, the macwrite document must be saved with its rulers and font information intact (not as TEXT ONLY) then transferred to the host system (see macget(1)).
Mwdvi will convert the macwrite document into dvi format and optionally submit the resultant file to dviimp(1) for printing on an electronic printer.
Mwdvi assumes that the file is to be printed using the TeX cmr fonts and substitutes Computer Modern Roman for all plain Macintosh fonts, Computer Modern Bold for all bold Macintosh fonts and Computer Modern Italic for all italic Macintosh fonts, at the appropriate point sizes. Since the fonts used to print the document are different from those used when viewing the document in macwrite, the spacing may come out somewhat differently. The spacing will be proportional, but probably not quite the same.
If a different mapping is desired, a font substitution file can be constructed using the following format:
macfontname [style] [pt size] -> texfontname [targ pt]
Where macfontname can be any of system, application, geneva, new_york, toronto, monaco, venice, london, athens, or san_fran, or a decimal number indicating the Macintosh internal number of the font to be substituted, style can be any of plain, bold, or italic, pt size is the size to be replaced, texfontname is the TeX font with which this font should be replaced, and targ pt is the point size at which the new font should be used.
For example:
london bold 12 -> cmb10 12
The name of the substitution file can be specified in the environment variable "MACFONTS" or with a command line option (that overrides any environment variable setting).
The options are:
If spooling is requested and no target file is indicated, mwdvi will use a temporary file for the duration of the program.
