<p>Starting with Ant 1.6, this task also supports nested <a
href="../CoreTypes/filelist.html">filelist</a>s.</p>
+<p>By default this task will use a single invocation of the underlying
+chmod command. If you are working on a large number of files this may
+result in a command line that is too long for your operating system.
+If you encounter such problems, you should set the maxparallel
+attribute of this task to a non-zero value. The number to use highly
+depends on the length of your file names (the depth of your directory
+tree) and your operating system, so you'll have to experiment a
+little. POSIX recommends command line length limits of at least 4096
+characters, this may give you an approximation for the number you
+could use as initial value for these experiments.</p>
