GNU Parallel 20110322 (the Japan release) released

GNU Parallel 20110322 (the Japan release) has been released. It is
available for download at: http://ftp.gnu.org/gnu/parallel/

New in this release:

* --tollef to be switch compatible with Tollef's parallel. This will
  cause -l to mean --load, and the argument separator will be --
  instead of :::

* --gnu will force GNU Parallel to behave like GNU Parallel even if
  --tollef is set.

* Site wide config file: /etc/parallel/config

  This should solve the issue with some packagers renaming GNU
  Parallel to gparallel to avoid the naming conflict.

  By putting --tollef in the site wide config file you can deinstall
  Tollef's parallel and install GNU Parallel instead without any
  change for users or scripts. This is useful for packagers that
  currently rename GNU Parallel or simply do not distribute GNU
  Parallel because the command name conflicts with Tollef's parallel.

* -L 0 -n 0, and -N 0 implemented. They will read one argument,
  but insert 0 arguments on the command line. Useful if you just want
  to run the same command with the same arguments a number of times.

* GNU Parallel is now in Fink. Thanks to Jesse Alama.

* Opscode Cookbook for Chef. Thanks to Joshua Timberman.

* GNU Parallel will be presented at:
  - LUGA, Augsburg, 2011-03-26, http://www.luga.de/Aktionen/LIT-2011/Programm
  - OSAA.dk, Aarhus, 2011-04-12

* Video of presentation from FSCONS 2010-11-07. The presenter was
  _really_ hoarse that day (Something to do with loads of alcohol the
  night before). http://vimeo.com/20838834

* Review with examples in German. Thanks to M. Nieberg.

= About GNU Parallel =

GNU Parallel is a shell tool for executing jobs in parallel using one
or more computers. A job is can be a single command or a small script
that has to be run for each of the lines in the input. The typical
input is a list of files, a list of hosts, a list of users, a list of
URLs, or a list of tables. A job can also be a command that reads from
a pipe. GNU Parallel can then split the input and pipe it into
commands in parallel.

If you use xargs and tee today you will find GNU Parallel very easy to
use as GNU Parallel is written to have the same options as xargs. If
you write loops in shell, you will find GNU Parallel may be able to
replace most of the loops and make them run faster by running several
jobs in parallel.

GNU Parallel makes sure output from the commands is the same output as
you would get had you run the commands sequentially. This makes it
possible to use output from GNU Parallel as input for other programs.
