+%description
+pkgconfig is a Python module to interface with the pkg-config command line
+tool and supports Python 2.6+.
+
+It can be used to
+
+* check if a package exists
+* check if a package meets certain version requirements
+* query CFLAGS and LDFLAGS
+* parse the output to build extensions with setup.py
+
+If pkg-config is not on the path, raises EnvironmentError.
