+ * formats. Also includes classes for compressing and decompressing data using
+ * the DEFLATE compression algorithm, which is used by the ZIP and GZIP file
+ * formats. Additionally, there are utility classes for computing the CRC-32,
+ * CRC-32C and Adler-32 checksums of arbitrary input streams.
