 .\" $FreeBSD$
-This is an experimental build system.
+This is an alternate build system.
 For details see
 https://www.crufty.net/sjg/docs/freebsd-meta-mode.htm.
 Build commands can be seen from the top-level with:
 .Dl make show-valid-targets
 The build is driven by dirdeps.mk using
 .Va 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
 .Xr make 1
 recursively reads
 .Va DIRDEPS
 from
 .Pa Makefile.depend ,
 computing a graph of tree dependencies from the current origin.
 Setting
 .Va NO_DIRDEPS
 skips checking dirdep dependencies and will only build in the current
 and child directories.
 .Va NO_DIRDEPS_BELOW
 skips building any dirdeps and only build the current directory.
 .Pp
 This also utilizes the
 .Va WITH_META_MODE
 logic for incremental builds.
 .Pp
 The build hides commands executed unless
 .Va NO_SILENT
 is defined.
 .Pp
 Note that there is currently no mass install feature for this.
+This build is designed for producing packages, that can then be installed
+on a target system.
 .Pp
+The implementation in FreeBSD is incomplete.
+Competion would require leaf directories for building each kernel
+and package so that their dependencies can be tracked.
