+# Script to invoke the FirmWorks build facility.
+# Usage:  build [-c|d|h|q|t|v] [target-name]
+#
+# This script automates the process of setting the BP and HOSTDIR
+# environment variables and parses the option flags [-c|d|h|q|t|v].
+
+# In order to run the build facility without this script:
+# Set the BP environment variable to the firmware root directory
+# Set the HOSTDIR environment variable to ${BP}/cpu/<cpuname>/<osname>,
+#   e.g. ${BP}/cpu/arm/Linux
+# Execute:
+#    ${HOSTDIR}/forth ${HOSTDIR}/../native.dic
+# At the "ok" prompt, type:
+#    build <target-name>
+# or
+#    tag <target-name>
+
+# Set BP by searching upward for the firmware root directory
