The files in this directory constitute the distribution of PSLaTeX, a
set of extensions and changes to LaTeX to make it PostScript-based.
Instructions can be found in pslatex.tex; this can be processed with
LaTeX (ignore warnings). When PSLaTeX is built, reprocess the
pslatex.tex using that. Users should also read pslatex.tex; gurus may
wish to read fonts.tex also.
To print DVI files produced by PSLaTeX you must have a DVI to
PostScript processor capable of using unmapped device-resident fonts.
Additionally, you may have to modify the header file downloaded to
your PostScript device as per the instructions in pslatex.tex. Things
are much easier with dvips, 'cos that's what I use.

Hints on DVI->PostScript convertors (for those not using dvips)
There are many, many DVI to PostScript convertors available now, each
with a different set of features. To guide you in choosing one to use
with PSLaTeX, you should bear the following in mind:
- LaTeX uses the Computer Modern (CM) fonts, for which PK, GF, or PXL
files are provided as part of the TeX distribution. The files
contain the bitmaps used to print each glyph in a font. PSLaTeX
uses fonts resident within the PostScript printing engine, and does
not need bitmaps for these fonts, only width information in the
form of a TeX Metric File (TFM). Indeed, bitmaps for these fonts
are not generally available.
Therefore, a convertor to be used with PSLaTeX must recognise that
some fonts are resident within the printing engine, and not attempt
to download bitmaps.
- As mentioned in the document that describes font usage in PSLaTeX,
some of the fonts used are derived (by simple geometric
transformations, implemented in PostScript) from the existing
fonts. Oblique fonts are made by "sloping" an upright font,
SmallCaps fonts contain the upper-case glyphs from an existing font
reduced by 20%, etc. It would be nice if such fonts had been
designed from scratch and made available to the general public, but
they haven't been, and we're stuck with the situation. Hence some
PostScript needs to be sent to the printer to "generate" these
fonts. Suitable PostScript can be found in makefonts.ps, and this
can be tacked onto the end of any existing header file that your
convertor uses.
