+/*
+ * DictZip Block driver for dictzip enabled gzip files
+ *
+ * Use the "dictzip" tool from the "dictd" package to create gzip files that
+ * contain the extra DictZip headers.
+ *
+ * dictzip(1) is a compression program which creates compressed files in the
+ * gzip format (see RFC 1952). However, unlike gzip(1), dictzip(1) compresses
+ * the file in pieces and stores an index to the pieces in the gzip header.
+ * This allows random access to the file at the granularity of the compressed
+ * pieces (currently about 64kB) while maintaining good compression ratios
+ * (within 5% of the expected ratio for dictionary data).
+ * dictd(8) uses files stored in this format.
+ *
+ * For details on DictZip see http://dict.org/.
