This is the Debian GNU/Linux prepackaged version of the netCDF Operators (NCO). This package was originally assembled by Brian Mays from software obtained from ftp://ftp.cgd.ucar.edu/pub/zender/nco NCO package modifications for Debian GNU/Linux made from 1999--2002 are Copyright (C) Brian Mays and were released under the GPL (on Debian systems see "/usr/share/common-licenses/GPL"). Beginning March, 2003, Charlie Zender and Rorik Peterson took over NCO Debian package maintenance and merged the code back upstream. More information at package homepage http://nco.sourceforge.net On June 15, 2003, Charlie Zender changed the NCO license, except where explicitly noted otherwise, from GPL to GPL version 2 (not any later version). Also at this time the explicit exceptions to the GPL for compatibility with the HDF, netCDF, OPeNDAP, and UDUnits licenses were formally introduced. On July 22, 2007, Charlie Zender changed the NCO licenses, except where explicitly noted otherwise, from GPL2 to GPL3 (for code) and from FDL 1.1 (or any later version) to FDL 1.2 (or any later version) for documentation. On January 20, 2009, Charlie Zender changed the NCO license for documentation, except where explicitly noted otherwise, from FDL 1.2 (or any later version) to FDL 1.3 (or any later version). On July 15, 2009, Charlie Zender added Benjamin Sittler and John Burkhardt to this copyright file to reflect their copyrights. Both retain copyright to their work which is licensed BSD-style (freely redistributable so long as copyright notices are maintained). On July 15, 2009, Charlie Zender received copyright assignments from Henry Butowsky and Karen Schuchardt. Their names were removed from the copyright statements in the files where they had been listed: nco_msa.c, nco_msa.h, and nco_aux.c. On January 26, 2010, Charlie Zender removed John Burkhardt from this copyright file after removing his gamma function code (nco_gmm.c) from the source.
