Subject: Announcing CWP/SU Release 31
CWP Software Update: CWP/SU Release 31: 19 October 1997 (31th edition)
The new compressed tars are available at our anonymous ftp
Internet address: ftp.cwp.mines.edu
or
[138.67.12.4]
The directory path is: pub/cwpcodes
The files are also available on the World Wide Web at:
http://www.cwp.mines.edu/cwpcodes/
The files you will need are (xx stands for the number of
the current release):
README_BEFORE_UNTARRING
untar_me_first.xx.tar.Z --- contains README and Portability information
cwp.su.all.xx.tar.Z --- contains the source code for the release
documentation.xx.tar.Z --- contains the SU Users Manual
documentation.xx.tar.Z --- contains the SU Users Manual
For incremental updating, instead take:
README_TO_UPDATE
update.yy.to.xx.tar.Z
update.list
NOTE: gzipped versions (untar_me_first.xx.tar.gz, etc.) are now available.
Is your ftp slow? Then try:
http://www.cwp.mines.edu/cwpcodes/outside_usa
or
ftp.cwp.mines.edu path: pub/cwpcodes/outside_usa
for the full distribution, in smaller files.

================================================================
New, Continued, and Expanded Support:
================================================================
I would like to thank the Gas Research Institute for its new
support for Seismic Unix.
I would also like to thank the Society of Exploration Geophysicists
(SEG) for their expanded support of SU through a generous
grant from the SEG Foundation.
My thanks also goes to the Consortium Project on Seismic Inverse
Methods for Complex Structures at the Center for Wave Phenomena
for its continuing financial support of the SU project.

What's New in SU:
================================================================
Global changes:
================================================================
Thanks to Stew Levin of Mobil for supplying a vast collection of
changes to further implement tighter coding standards. Practically
every code has been modified as a result of Stew's important
contributions.
A special thanks, also, to Toralf Foerster of the Baltic Sea Research
Institute in Rostock, Germany for many helpful bug fixes and
suggestions for the package.
