2 This is an experimental build system.

5 Build commands can be seen from the top-level with:
6 .Dl make show-valid-targets
7 The build is driven by dirdeps.mk using
10 Makefile.depend files found in each directory.
12 The build can be started from anywhere, and behaves the same.
13 The initial instance of
19 computing a graph of tree dependencies from the current origin.
22 skips checking dirdep dependencies and will only build in the current
23 and child directories.
25 skips building any dirdeps and only build the current directory.
27 This also utilizes the
29 logic for incremental builds.
31 The build hides commands executed unless
35 Note that there is currently no mass install feature for this.
