The file compress.c contains (slightly modified) source code that
originally came from gzip-1.2.4, copyright (C) 1992-1993 by Jean-loup
Gailly. This gzip code is distributed under the GNU General Public
Licence and thus requires that any software that uses the CFITSIO
library (which in turn uses the gzip code) must conform to the
provisions in the GNU General Public License. A copy of the GNU
licence is included at the beginning of compress.c file.
An alternate version of the compress.c file (called compress_alternate.c)
is provided for users who want to use the CFITSIO library but are
unwilling or unable to publicly release their software under the terms
of the GNU General Public License. This alternate version contains
non-functional stubs for the file compression and uncompression
routines used by CFITSIO. Replace the file 'compress.c' with
'compress_alternate.c' before compiling the CFITSIO library. This will
produce a version of CFITSIO which does not support reading or writing
compressed FITS files but is otherwise identical to the standard
version.
