+Subject: [PATCH] setup.py: Fallback to use the system hiredis library.
+
+Fixes #158 fully, including using a system-prodived hiredis.
+
+When the hiredis git submodule hasn't been initialized, print a
+message about it, and attempt to link against the a system-provided
+hiredis library instead.
+
+* setup.py (is_hiredis_bundled): New procedure.
+(get_hiredis_bundled_sources): Likewise.  Print a message when
+bundled_hiredis_sources is empty.
+(get_sources): Adjust to use the above procedure.
+(get_linker_args): Add -lhiredis when the bundled hiredis is not used.
