+# workonsrc.bbclass enables use of an existing source tree, usually workon to
+# the build system to build a piece of software rather than the usual fetch/unpack/patch
+# process.
+#
+# To use, add workonsrc to the global inherit and set WORKONSRC to point at the
+# directory you want to use containing the sources e.g. from local.conf for a recipe
+# called "myrecipe" you would do:
+#
+# INHERIT += "workonsrc"
+# WORKONSRC_pn-myrecipe = "/path/to/my/source/tree"
+#
+# In order to make this class work for both target and native versions (or with
+# multilibs/cross or other BBCLASSEXTEND variants), B is set to point to a separate
+# directory under the work directory (split source and build directories). This is
+# the default, but the build directory can be set to the source directory if
+# circumstances dictate by setting WORKONSRC_BUILD to the same value, e.g.:
+#
+# WORKONSRC_BUILD_pn-myrecipe = "/path/to/my/source/tree"
+#
