Subject: [PATCH] Accepting request 495383 from home:jengelh:branches:Archiving

- Trim/update description. Redo .pc file generation so that the
  resulting file looks like other .pc files on openSUSE.

-LZMA SDK provides the documentation, samples, header files, libraries,
-and tools you need to develop applications that use LZMA compression.
+LZMA SDK provides documentation, samples, header files, libraries,
+and tools for developing applications with LZMA support.
 
-LZMA is default and general compression method of 7z format
-in 7-Zip compression program (www.7-zip.org). LZMA provides high
-compression ratio and very fast decompression.
-
-LZMA is an improved version of famous LZ77 compression algorithm.
-It was improved in way of maximum increasing of compression ratio,
-keeping high decompression speed and low memory requirements for
-decompressing.
+LZMA uses a dictionary compression algorithm (a variant of LZ77, with
+huge dictionary sizes and special support for repeatedly used match
+distances), whose output is then encoded with a range encoder, using
+a model to make a probability prediction of each bit.
+LZMA yields around 20%% better compression when operating at approximately
+zlib's speed, and around 40%% when trading more time.
