==Madagascar Trivia==

===Why the Name "Madagascar"?===

[http://ahay.org/blog/2006/04/19/madagascar/ Whimsy, really]. It seems easier to remember than the previous name "RSF", and it provides us interesting [http://ahay.org/blog/2008/10/21/ahay/ mascots].

===History=== 

Madagascar was first publicly presented at the [[Conferences#Vienna_2006_.28EAGE.29|EAGE Workshop]] in Vienna in June 2006. The work on the package (previously named RSF) was started by Sergey Fomel in 2003. Since then, many people have contributed to it. See [https://github.com/ahay/src/blob/master/AUTHORS.txt AUTHORS.txt] for an incomplete list.

While being written primarily from scratch, Madagascar borrows ideas from the design of [http://sepwww.stanford.ed/doku.php?id=sep:software:seplib SEPlib], a package maintained by Bob Clapp at the Stanford Exploration Project (SEP). Generations of SEP students and researchers contributed to SEPlib. The most significant contributions came from Rob Clayton, Jon Claerbout, Dave Hale, Stew Levin, Rick Ottolini, Joe Dellinger, Steve Cole, Dave Nichols, Martin Karrenbach, Biondo Biondi, and Bob Clapp.

Madagascar also borrows ideas from [http://timna.mines.edu/cwpcodes/ Seismic Unix] (SU), an open-source package maintained by John Stockwell at the Center for Wave Phenomena (CWP) at the Colorado School of Mines (Stockwell, 1997<ref>Stockwell, J. W.,  1997, Free software in education: A case study of CWP/SU: Seismic Unix: The Leading Edge, '''16''', 1045--1049.</ref>;Stockwell, 1999<ref>--------, 1999, The CWP/SU: Seismic Un*x package: Computers and  Geosciences, '''25''', 415--419.</ref>). Main contributors to SU included Einar Kjartansson, Shuki Ronen, Jack Cohen, Chris Liner, Dave Hale, and John Stockwell. SU adopted an open-source BSD-style license starting with release 40 (April 10, 2007).
