+# USAGE:
+#
+# 1. TOPDIR and APPDIR must be defined on the make command line: TOPDIR
+# is the full path to the nuttx/ directory; APPDIR is the full path to
+# the apps/ directory. For example:
+#
+# make -f Makefile.host TOPDIR=/home/me/projects/nuttx
+# APPDIR=/home/me/projects/apps
+#
+# 2. Add CONFIG_DEBUG=1 to the make command line to enable debug output
+# 3. Make sure to clean old target .o files before making new host .o
+# files.
