+	  <http://www.tldp.org/docs.html#howto>.
+
+	  Note that the answer to this question doesn't directly affect the

+	  Say Y here if you intend to attach a Fujitsu FMV-J18x or compatible
+	  PCMCIA (PC-card) Ethernet card to your computer.
+
+	  To compile this driver as a module, choose M here: the module will be
+	  called fmvj18x_cs.  If unsure, say N.

+
+    A fmvj18x (and its compatibles) PCMCIA client driver
+
+    Contributed by Shingo Fujimoto, shingo@flab.fujitsu.co.jp
+
+    TDK LAK-CD021 and CONTEC C-NET(PC)C support added by 
+    Nobuhiro Katayama, kata-n@po.iijnet.or.jp
+
+    The PCMCIA client code is based on code written by David Hinds.
+    Network code is based on the "FMV-18x driver" by Yutaka TAMIYA
+    but is actually largely Donald Becker's AT1700 driver, which
