+# This board support package is not a board support package at all, but
+# a means to build the RTEMS kernel without using a specific BSP.
+#
+# You should be able to build to build this BSP for any cpu type.
+#
+# You must provide the standard BSP type functions and support yourself
+# externally to RTEMS.
+#
+# This BSP is intended to be used by people who fit one or more of the 
+# categories below :
+#
+# 1) using custom hardware of little use or interest to others. If you 
+#    intend to use hardware available to others, please create a BSP 
+#    and send to OARCorp.
+#
+# 2) production code cannot depend on software which can change. BSP code
+#    can change with-out notice, while RTEMS has very tightly defined 
+#    interfaces which do not change.
+#
+# 3) the need to extend or change an existing BSP in ways which are not
+#    of interest to others or the BSP maintainer.
+#
+# I fit all the above.
