+# To use it do the following:\r
+# - Install the latest version of global\r
+# - Enable SOURCE_BROWSER and USE_HTAGS in the config file\r
+# - Make sure the INPUT points to the root of the source tree\r
+# - Run doxygen as normal\r
+#\r
+# Doxygen will invoke htags (and that will in turn invoke gtags), so these\r
+# tools must be available from the command line (i.e. in the search path).\r
+#\r
+# The result: instead of the source browser generated by doxygen, the links to\r
+# source code will now point to the output of htags.\r
+# The default value is: NO.\r
+# This tag requires that the tag SOURCE_BROWSER is set to YES.\r
