Since makeman turns all options on, we need to guard somethings from
make(showconfig)

+Enable building in meta mode.
+.Pp
+The build is driven by dirdeps.mk using DIRDEPS stored in
+Makefile.depend files found in each directory.
+.Pp
+The build can be started from anywhere, and behaves the same.
+The initial instance of make recursively reads DIRDEPS from Makefile.depend
+computing a graph of tree dependencies from the current origin.
+See http://www.crufty.net/help/sjg/dirdeps.htm
+.Pp
+As each target is made
+.Xr make 1
+produces a meta file which is used to capture (and compare)
+the command line,
+as well as any command output.
+If
+.Xr filemon 4
+is available the meta file will also capture a record of syscalls
+used to produce the target.
