-\fBtos-storage-pxa27xp30\fR reads a user specification describing the
-layout of storage volumes on an embedded P30 flash in the Intel Xscale
-PXA27X series processor, and generates code describing that layout for
-use by the TinyOS 2.0 storage subsystem. The user specification is in
-XML and is read from standard input. The code is written to standard
-output.
+\fBtos-storage-pxa27xp30\fR reads a user specification describing the layout of
+storage volumes on an embedded P30 flash in the Intel Xscale PXA27X series
+processor, and generates code describing that layout for use by the TinyOS 2.0
+storage subsystem. The user specification is in XML and is read from standard
+input. With all options, the code for a header file is written to standard
+output. With the optional \fB-t\fR flag specified, a VolumeMapC.nc file is
+generated that provides interfaces to all the storage volume abstractions
+defined in the XML file.

+The mandatory \fIplatform-directory\fR argument should specify the platform
+directory for the current compilation target; this is necessary for the correct
+handling of file include statements in the XML input.
