+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# If set to a non-null value, in-source builds will be enabled.
+# If unset, the default is to use in-source builds when python_prepare()
+# is declared, and out-of-source builds otherwise.
+#
+# If in-source builds are used, the eclass will create a copy of package
+# sources for each Python implementation in python_prepare_all(),
+# and work on that copy afterwards.
+#
+# If out-of-source builds are used, the eclass will instead work
+# on the sources directly, prepending setup.py arguments with
+# 'build --build-base ${BUILD_DIR}' to enforce keeping & using built
+# files in the specific root.
