+Subject: [PATCH] Add an option to disable bzip2 support
+
+The explicit switch is still on by default, but this way it's possible
+to explicitly disable bzip2 support even if bzip2 is available on the
+system.
+
+This is useful if bzip2 is not needed, but would automatically lead to
+an unwanted dependency.
