Through an unfortunate oversight, the CD-ROM distributed in the first printing of _Programming Python_ contains several errors. On UNIX: Several README files have erroneous permissions. On Windows and Macintosh: A few directories contain files whose names differ only in case /cdrom/www.python.org/doc/lib/TERMIOS.html /cdrom/www.python.org/doc/lib/termios.html /cdrom/www.python.org/doc/lib/Types.html /cdrom/www.python.org/doc/lib/types.html /cdrom/www.python.org/doc/life-preserver/Index.html /cdrom/www.python.org/doc/life-preserver/index.html /cdrom/www.python.org/doc/old/lib/TERMIOS.html /cdrom/www.python.org/doc/old/lib/termios.html /cdrom/www.python.org/doc/old/lib/Types.html /cdrom/www.python.org/doc/old/lib/types.html Since Windows and Macintosh file systems are not case sensitive, one or both of these files may be inaccessible. In an effort to compensate for these problems, we've placed the affected files on our ftp site. Please accept our sincerest apologies if you have been inconvenienced by these problems. If you have any questions or concerns, please do not hesitate to contact us.
