+# class ExternalProject
+
+# Handles build of an external project
+
+# Build of an external typically uses three gbuild classes:
+# ExternalProject, ExternalPackage or Package, and UnpackedTarball. The
+# first step is to prepare sources using UnpackedTarball. The tarball is
+# passed to an ExternalProject, which handles the build proper and the
+# results are delivered by an ExternalPackage (or Package, again;
+# Package is sufficient if no files--e.g., headers--from the unpacked
+# tarball need to be delivered.)
+#
+# An ExternalProject always uses one UnpackedTarball with the same name.
+# The dependency structure ensures that any change on a dependency
+# of the ExternalProject will cause the UnpackedTarball to be unpacked
+# again, so the ExternalProject always does a clean build and is not at
+# the mercy of the external's build system's dubious incremental builds.
+#
+# ExternalProject target
+# => ExternalProject state target(s) (these actually build stuff)
+#    => UnpackedTarball target (unpack the tarball)
+#       => UnpackedTarball prepare target
+#          => ExternalProject prepare target
+#             => stuff the external depends upon
+#
+# ExternalProject has no gbuild abstraction for actually building the
+# external code, so it is necessary to define rule(s) and recipe(s) to
+# handle it. It does not matter if there are several rules handling
+# separate phases of the build (e.g., configure, build, install) or if
+# the whole build is handled by one rule.
+#
+# ExternalProject uses two directories during the build: state dir
+# serves to keep file targets that mark state of the build progress
+# (e.g., "configure done", "build done") and the targets are accessible
+# via gb_ExternalProject_get_state_target. It is highly advised to
+# register them using gb_ExternalProject_register_targets. The second
+# directory is work dir, accessible only from recipes via variable
+# $(EXTERNAL_WORKDIR).
