Whenever the program needs to locate a file, it first searches the address in the bookkeeping file. If it doesn’t find the address there, the program embarks on a search throughout the physical directories of its platform. <!--l. 5565--><p class="indent"> The program places the bookkeeping file at the first applicable location of the following list. </p><!--l. 5568--><p class="indent"> </p><ol type="1" > <li>The pointer specified by an optional ‘<span class="cmtt-10">-l</span>’ switch provided to the invocation of the <span class="cmtt-10">tex4ht </span>program. </li> <li>A file named <span class="cmtt-10">tex4ht.fls </span>in the directory specified by an optional environment variable named <span class="cmtt-10">TEX4HTWR</span>. </li> <li>The location specified by an optional ‘<span class="cmtt-10">l</span>’ record provided in the environment file. </li> <li>A file named <span class="cmtt-10">tex4ht.fls </span>in the work directory. </li></ol> 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">TEX4HTWR</span>. The address stored in the latter environment variable may also start with a single character ‘<span class="cmtt-10">~</span>’. <!--l. 5595--><p class="indent"> The bookkeeping file must have writable access mode, and the directory which contains the file should have a compatible access mode. </p><!--l. 5599--><p class="indent"> The bookkeeping file is a dynamically constructed variant of the ls-R file of kpathsea.
