 Pcompress is a utility to do compression and decompression in parallel by
 splitting input data into chunks. It has a modular structure and includes
-support for multiple algorithms like LZMA, Bzip2, PPMD, etc, with SKEIN
-checksums for data integrity. It can also do Lempel-Ziv pre-compression
+support for multiple algorithms like LZMA, Bzip2, PPMD, etc, with SKEIN/
+SHA checksums for data integrity. It can also do Lempel-Ziv pre-compression
 (derived from libbsc) to improve compression ratios across the board. SSE
 optimizations for the bundled LZMA are included. It also implements
 chunk-level Content-Aware Deduplication and Delta Compression features
 based on a Semi-Rabin Fingerprinting scheme. Delta Compression is done
 via the widely popular bsdiff algorithm. Similarity is detected using a
-custom hashing of maximal features of a block. When doing chunk-level
-dedupe it attempts to merge adjacent non-duplicate blocks index entries
-into a single larger entry to reduce metadata. In addition to all these it
-can internally split chunks at rabin boundaries to help dedupe and
-compression.

 It has low metadata overhead and overlaps I/O and compression to achieve
 maximum parallelism. It also bundles a simple slab allocator to speed
 repeated allocation of similar chunks. It can work in pipe mode, reading
-from stdin and writing to stdout. It also provides some adaptive compression
-modes in which multiple algorithms are tried per chunk to determine the best
-one for the given chunk. Finally it supports 14 compression levels to allow

+algorithms per chunk. Finally it supports 14 compression levels to allow
 for ultra compression modes in some algorithms.
 
 Pcompress also supports encryption via AES and uses Scrypt from Tarsnap

 NOTE: This utility is Not an archiver. It compresses only single files or
       datastreams. To archive use something else like tar, cpio or pax.
