+Note about konqueror
+--------------------
+
+When 'konqueror' is specified by the a command line option or a
+configuration variable, we launch 'kfmclient' to try to open the HTML
+man page on an already opened konqueror in a new tab if possible.
+
+For consistency, we also try such a trick if 'brower.konqueror.path' is
+set to something like 'A_PATH_TO/konqueror'. That means we will try to
+launch 'A_PATH_TO/kfmclient' instead.
+
+If you really want to use 'konqueror', then you can use something like
+the following:
+
+------------------------------------------------
+	[web]
+		browser = konq
+
+	[browser "konq"]
+		cmd = A_PATH_TO/konqueror
+------------------------------------------------
+
