Re: [Bug-tar] .lz also can be extension for .lzma files

[Karl Berry]

    As for successors of lzma, I may be confused, but hasn't the
    original author released his own successor? 7z?

I don't think 7z is the successor of lzma.

Igor Pavlov had the idea for LZMA (it's essentially zip with different
parameters, as I understand it) originally and included it in 7-zip.
Then Lasse Collin wrote lzma-utils which was the same compression
algorithm but was not an archive format (as the previous poster already
replied).

An anonymous programmer wrote p7zip, essentially support for 7-zip for
Unixish systems (it included the nonfree unrar v3 support).

Then Antonio Diaz Diaz devised lz, which again is the same basic
compression algorithm as lzma but with a proper magic number, etc.  It
is not an archive format.

Igor and Lasse collaborated on creating the xz format, which is the
successor to lzma.  There's no reason to use lzma any more.  (Their xz
was released a few months after Antonio's lz.)

The xz-utils (and previous lzma-utils) from Lasse are gzip/bzip-ish in
terms of options, working with pipes, etc.

I don't know if Igor has updated 7z or released a new archive format
with xz support.
