+Usage: bsdconfig @PROGRAM_NAME@ [OPTIONS] [include ...]
+
+OPTIONS:
+	-a    Always use color even when output is not to a terminal.
+	-f    Show functions for selected includes.
+	-F pattern
+	      If `-f', only print functions matching pattern. Without `-f'
+	      print only includes containing functions matching pattern.
+	-h    Print this usage statement and exit.
+	-n    Disable the use of color.
+
+EXAMPLES:
+	View a list of available includes:
+
+		bsdconfig @PROGRAM_NAME@
+
+	View functions for all available includes (function names are
+	highlighted):
+
+		bsdconfig @PROGRAM_NAME@ -f
+
+	View functions with less(1) (function names are not highlighted):
+
+		bsdconfig @PROGRAM_NAME@ -f | less
+
+	View functions with less(1) and color:
+
+		bsdconfig @PROGRAM_NAME@ -af | less -R
+
+	View functions from `common.subr':
+
+		bsdconfig @PROGRAM_NAME@ common.subr
+
+	NB: The `-f' flag is implied when given an include.
+
+	Show only functions containing the word `show' in common.subr:
+
+		bsdconfig @PROGRAM_NAME@ -F show common
+
+	NB: The `.subr' suffix on the end of the include is optional.
