+%global pkg_name bytestring-trie
+
+%global common_summary An efficient finite map from (byte)strings to values
+
+%global common_description The implementation is based on big-endian patricia trees, \
+like "Data.IntMap". We first trie on the elements of \
+"Data.ByteString" and then trie on the big-endian bit \
+representation of those elements. Patricia trees have \
+efficient algorithms for union and other merging operations, \
+but they're also quick for lookups and insertions.
