+# This module defines rules to handle generation of various outputs from source
+# files documented with doxygen comments. The supported transformations are:
+#
+# * Source -> Doxygen XML -> BoostBook XML
+# * Source -> Doxygen HTML
+#
+# The type of transformation is selected based on the target requested. For
+# BoostBook XML, the default, specifying a target with an ".xml" suffix, or an
+# empty suffix, will produce a <target>.xml and <target>.boostbook. For Doxygen
+# HTML specifying a target with an ".html" suffix will produce a directory
+# <target> with the Doxygen html files, and a <target>.html file redirecting to
+# that directory.
