given order.
</p><!--l. 6034--><p class="indent">
</p><ul type="disc" >
<li>The directory named in the <a
href="mn29.html" >command line</a> of tex4ht, identified with the prefix ‘<span class="cmtt-10">-t</span>’.
<!--l. 6041--><p class="noindent"></p></li>
<li>The directory identified with the character ‘<span class="cmtt-10">t</span>’ in the tex4ht.env file.
<!--l. 6044--><p class="noindent"></p></li>
<li>The directory whose name is fed into tex4ht.c during compilation time, through the program variable
<a
href="mn46.html#x-TFMDIR" name="TFMDIR">TFMDIR</a>.
<!--l. 6049--><p class="noindent"></p></li>
<li>In the directory holding the executable <span class="cmtt-10">tex4ht </span>(only for MS Windows).
</li></ul>
A given address may start with the character ‘<span class="cmtt-10">~</span>’ or the character pair ‘<span class="cmtt-10">~~</span>’. The single character ‘<span class="cmtt-10">~</span>’ is
interpreted to be the directory address of the root, provided in an environment variable named <span class="cmtt-10">HOME</span>. The
character pair ‘<span class="cmtt-10">~~</span>’ is interpreted to be a directory address provided in an environment variable named
<span class="cmtt-10">TEX4HTTFM</span>. The address stored in the latter environment variable may also start with a single character
‘<span class="cmtt-10">~</span>’.
<!--l. 6064--><p class="indent"> The optional environment variable <span class="cmtt-10">TEX4HTTFM </span>may hold one or more addresses. The addresses must be
separated by a character which does not appear in the addresses, and that character must also delimit the content
at the start and end points.
</p><!--l. 6070--><p class="indent"> The system variable <a
href="mn46.html#x-MAXFONTS" name="MAXFONTS">MAXFONTS</a> of tex4ht.c places a limit on the number of fonts allowed in the documents.
The default setting doesn’t provide such a limit.
</p><!--l. 6074--><p class="indent"> If the program <span class="cmtt-10">tex4ht.c </span>is compiled with the ‘<span class="cmtt-10">-DKPATHSEA</span>’ switch on, TeX4ht ignores its own search and
delegate it to the kpathsea utility.
