<p>This class holds a font’s texname and size, supports comparison,
and knows the widths of glyphs in the same units as the AFM file.
There are also internal attributes (for use by dviread.py) that
are <em>not</em> used for comparison.</p>

<p class="rubric">Notes</p>
<p>For historical reasons, TeX knows many Type-1 fonts by different
names than the outside world. (For one thing, the names have to
fit in eight characters.) Also, TeX’s native fonts are not Type-1
but Metafont, which is nontrivial to convert to PostScript except
as a bitmap. While high-quality conversions to Type-1 format exist
and are shipped with modern TeX distributions, we need to know
which Type-1 fonts are the counterparts of which native fonts. For
these reasons a mapping is needed from internal font names to font
file names.</p>
<p>A texmf tree typically includes mapping files called e.g.
<code class="file docutils literal"><span class="pre">psfonts.map</span></code>, <code class="file docutils literal"><span class="pre">pdftex.map</span></code>, or <code class="file docutils literal"><span class="pre">dvipdfm.map</span></code>.
The file <code class="file docutils literal"><span class="pre">psfonts.map</span></code> is used by <strong class="program">dvips</strong>,
<code class="file docutils literal"><span class="pre">pdftex.map</span></code> by <strong class="program">pdfTeX</strong>, and <code class="file docutils literal"><span class="pre">dvipdfm.map</span></code>
by <strong class="program">dvipdfm</strong>. <code class="file docutils literal"><span class="pre">psfonts.map</span></code> might avoid embedding
the 35 PostScript fonts (i.e., have no filename for them, as in
the Times-Bold example above), while the pdf-related files perhaps
only avoid the “Base 14” pdf fonts. But the user may have
configured these files differently.</p>
