by lzma archive, you probably mean a lzma-compressed tar archive.
You can extract them with
lzma -dc compressedarchive.tar.lzma | tar -xv -f -
or, if your version of tar supports it,
tar --lzma -xv -f compressedarchive.tar.lzma

The command lzma comes from app-arch/lzma-utils, and these days the
distros ship it by default.

This command line can be simplified:
unlzma -c compressedarchive.tar.lzma | tar xv

Most better desktop archive managers (for example file-roller for GNOME)
can handle these archives nowadays.

why not directly

tar --lzma -xvf compressedarchive.tar.lzma

then? (I hope I got the syntax right)

I like to do things right (I love Math, exactness and rigor). From
tar's info page

If you don't specify this argument [the argument to -f] , then
`tar' will examine the
environment variable `TAPE'. If it is set, its value will be used as
the archive name. Otherwise, `tar' will use the default archive,
determined at the compile time. [...] If there is no tape drive
attached, or the default is not meaningful, then `tar' will print an
error message. The error message might look
roughly like one of the following:

tar: can't open /dev/rmt8 : No such device or address
tar: can't open /dev/rsmt0 : I/O error

To avoid confusion, we recommend that you always specify an archive file
name by using `--file=ARCHIVE-NAME' (`-f ARCHIVE-NAME') when writing
your `tar' commands.

Regarding old-style tar options (that is, tar options without a dash):

old style syntax makes it difficult to match
option letters with their corresponding arguments, and is often
confusing
[...]

This old way of writing `tar' options can surprise even experienced
users. For example, the two commands:

tar cfz archive.tar.gz file
tar -cfz archive.tar.gz file

are quite different.


So I use either tar --lzma -xv -f compressedarchive.tar.lzma or, when
using an old tar,
lzma -dc compressedarchive.tar.lzma | tar -xv -f -

The "correct" official tar syntax does not use '-'. If you like to be 100%
that a tar command should work, ddon't use '-' in front of options.

BTW: "star" autodetects 7z compression and calls the program "p7zip" to unpack
the archive transparently.

Yes, sure. That's why

% tar --lzma tvf /gentoo/distfiles/texlive-module-context-
vim.doc-2008.tar.lzma
tar: You must specify one of the `-Acdtrux' options
Try `tar --help' or `tar --usage' for more information.

just works. Or does it need to be -tvf? The "correct" syntax is the one used
by the version of tar one is using. For the most of us, this is GNU tar.

Bye...
