+#
+# NOTE: Do not set your platform to "BlueGeneQ-base".  This file is
+# included by the real platform files.  Use one of these two platforms
+# instead:
+#
+#     BlueGeneQ-dynamic  For dynamically linked executables
+#     BlueGeneQ-static   For statically linked executables
+#
+# The platform you choose doesn't affect whether or not you can build
+# shared or static libraries -- it ONLY changs whether exeuatbles are linked
+# statically or dynamically.
+#
+# This platform file tries its best to adhere to the behavior of the MPI
+# compiler wrappers included with the latest BG/P drivers.
+#
+
+#
+# This adds directories that find commands should specifically ignore
+# for cross compiles.  Most of these directories are the includeand
+# lib directories for the frontend on BG/P systems.  Not ignoring
+# these can cause things like FindX11 to find a frontend PPC version
+# mistakenly.  We use this on BG instead of re-rooting because backend
+# libraries are typically strewn about the filesystem, and we can't
+# re-root ALL backend libraries to a single place.
