Subject: GNU Parallel 2011XXXX released

GNU Parallel 2011XXXX has been released. It is available for
download at: http://ftp.gnu.org/gnu/parallel/

This is a major release as the --pipe option introduces a new way to
work. To learn about --pipe see the example section for uses of
--pipe.

But rest assured: No old functionality is changed.

New in this release:

* --pipe splits piped data into blocks. Each block is piped to a
  program for processing. The piping and the programs will be run in
  parallel. Useful if the data you want to process is data for a
  program and not arguments.

* --blocksize sets the blocksize in bytes for --pipe. The blocksize is
  approximate. It can deviate as much as the size of one record.
  Default is 1M.

* --recstart sets the regular expression matching the start of a
  record. Default is "".

* --recend sets the regular expression matching the end of a
  record. Default is "\n". To specify none use --recend "".

  If both --recstart and --recend are set, the end of a record must be
  followed immediately by a start of a record. This is useful if
  either recend or recstart can occur in the middle of a record.

* --output-as-files will put the output of the programs into files and
  instead of giving the output GNU Parallel will output the name of
  these files.

* -N set the number of records to read. If used with --blocksize
  the block read will at most be --blocksize. -N is much slower
  than --blocksize so avoid -N if performance is important.

* Advanced recursive example. Thanks to Ruarí Ødegaard.

* Bug fixes and man page updates.

= About GNU Parallel =

GNU Parallel is a shell tool for executing jobs in parallel using one
or more computers. A job is typically 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.

If you use xargs 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. If you use ppss or pexec you will find GNU Parallel
will often make the command easier to read.

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.
