I was wondering about whether xz-utils needed a middle paragraph to
bridge from this to XZ, but really it should be there from the start
as something more like:

    XZ is the successor to the Lempel-Ziv/Markov-chain Algorithm, which
    gives memory-hungry but powerful compression (often better than bzip2)
    and fast, easy decompression.

Boilerplate can be a pain if it's yards of advertising fluff, but
done well it can be handy - paragraph one, what this software
suite's all about; paragraph two, why you'd install this particular

(There's a counterargument that the payload should be in the first
line, but I'd say that's why we have a short description too.)

If the bulleted list is worth having (either in this description or
the -dev one) it sounds as if it would be along the lines of:
 * support for format-specific metadata (file magic for .xz files);
 * configurable memory usage (low settings still give good results);
 * can make use of extra memory during compression or decompression;
(I wish I could re-word that one as a noun phrase like the rest...)
 * crc32 integrity checking;
 * familiar zlib-like low-level operation;
(if you can get away with spinning that as an advantage)
 * support for variant compressor/decompressor implementations.

Oh, I should have connected the dots for myself about xz-lzma
providing the compatibility layer.
