+# This class is used like rm_work:
+# INHERIT += "rm_work_and_downloads"
+#
+# In addition to removing local build directories of a recipe, it also
+# removes the downloaded source. This is achieved by making the DL_DIR
+# recipe-specific. While reducing disk usage, it increases network usage (for
+# example, compiling the same source for target and host implies downloading
+# the source twice).
+#
+# Because the "do_fetch" task does not get re-run after removing the downloaded
+# sources, this class is also not suitable for incremental builds.
+#
+# Where it works well is in well-connected build environments with limited
+# disk space (like TravisCI).

+inherit rm_work
+
+# This would ensure that the existing do_rm_work() removes the downloads,
+# but does not work because some recipes have a circular dependency between
+# WORKDIR and DL_DIR (via ${SRCPV}?).
+# DL_DIR = "${WORKDIR}/downloads"
+
+# Instead go up one level and remove ourself.
