New in this release:
* niceload --sensor makes it possible to use a program to control if a
program should be suspended.
* --shebang-wrap makes is possible to parallelize scripts by putting

* GNU Parallel was part of the justification for Nordic Free Software
Award 2012
https://fsfe.org/news/2012/news-20121112-01.html
* --delay puts in a delay after starting each job. Useful to avoid
raceconditions and thundering herd problems.
* Dateien schneller packen und konvertieren mit GNU parallel
http://www.linux-community.de/Archiv/Tipp-der-Woche/Dateien-schneller-packen-und-konvertieren-mit-GNU-parallel
* --results now uses / as separator instead of TAB and thus creates
subdirs.
* Processing images from Lunar Reconnaissance Orbiter Narrow Angle
Camera http://lunokhod.org/?p=774
* niceload --sensor allows for negative numbers to signify a lower
number means the limit is lower.
* GNU Parallel is used in types2: Type and Hapax Accumulation Curves
http://www.cs.helsinki.fi/u/josuomel/types2/
* niceload --prg suspend a named program that is already running.
* GNU Parallel used in: A Hybrid Factor Analysis and Probabilistic
PCA-based system for Dictionary Learning and Encoding for Robust
Speaker Recognition

* niceload --pid suspend process id that is already running.
* Mapreduce avec parallel, cat et une redirection

* GNU Parallel for Large Batches of Small Jobs
