-    <title>Code Path Cache</title>
-    <p>The code server incorporates a code path cache. The cache
-      functionality is disabled by default. To activate it, start
-      the emulator with the command line flag <c>-code_path_cache</c>
-      or call <c>code:rehash()</c>. When the cache is created (or
-      updated), the code server searches for modules in the code path
-      directories. This may take some time if the the code path is long.
-      After the cache creation, the time for loading modules in a large
-      system (one with a large directory structure) is significantly
-      reduced compared to having the cache disabled. The code server
-      is able to look up the location of a module from the cache in
-      constant time instead of having to search through the code path
-      directories.</p>
-    <p>Application resource files (<c>.app</c> files) are also stored
-      in the code path cache. This feature is used by the application
-      controller (see
-      <seealso marker="application">application(3)</seealso>) to load
-      applications efficiently in large systems.</p>
-    <p>Note that when the code path cache is created (or updated), any
-      relative directory names in the code path are converted to
-      absolute.</p>
