+Theory of Operation
+
+Please see README for user documentation, and you should be familiar with
+that before trying to make sense of this.
+
+Buildman works by keeping the machine as busy as possible, building different
+commits for different boards on multiple CPUs at once.
+
+The source repo (self.git_dir) contains all the commits to be built. Each
+thread works on a single board at a time. It checks out the first commit,
+configures it for that board, then builds it. Then it checks out the next
+commit and builds it (typically without re-configuring). When it runs out
+of commits, it gets another job from the builder and starts again with that
+board.
+
+Clearly the builder threads could work either way - they could check out a
+commit and then built it for all boards. Using separate directories for each
+commit/board pair they could leave their build product around afterwards
+also.
+
+The intent behind building a single board for multiple commits, is to make
+use of incremental builds. Since each commit is built incrementally from
+the previous one, builds are faster. Reconfiguring for a different board
+removes all intermediate object files.
+
+Many threads can be working at once, but each has its own working directory.
+When a thread finishes a build, it puts the output files into a result
+directory.
+
+The base directory used by buildman is normally '../<branch>', i.e.
+a directory higher than the source repository and named after the branch
+being built.
+
+Within the base directory, we have one subdirectory for each commit. Within
+that is one subdirectory for each board. Within that is the build output for
+that commit/board combination.
+
+Buildman also create working directories for each thread, in a .bm-work/
+subdirectory in the base dir.
+
+As an example, say we are building branch 'us-net' for boards 'sandbox' and
+'seaboard', and say that us-net has two commits. We will have directories
+like this:
+
+us-net/ base directory
+ 01_of_02_g4ed4ebc_net--Add-tftp-speed-/
+ sandbox/
+ u-boot.bin
+ seaboard/
+ u-boot.bin
+ 02_of_02_g4ed4ebc_net--Check-tftp-comp/
+ sandbox/
+ u-boot.bin
+ seaboard/
+ u-boot.bin
+ .bm-work/
+ 00/ working directory for thread 0 (contains source checkout)
+ build/ build output
+ 01/ working directory for thread 1
+ build/ build output
+ ...
+u-boot/ source directory
