File Release Notes and Changelog

Release Name: 2003-06-02 for 2.1.36 and up

Notes:
Tested against octave-2.1.49.  Compiles for 2.1.36 and up.
Some functions will not work with Octave-2.1.39 or earlier.  
For versions prior to 2.1.35, use make -k to build whatever 
can be built ignoring the rest.

*** WARNING *** if installing in a user directory, octave may crash
immediately on startup.  Either install into a system directory, or
remove the comm/PKG_ADD and sparse/PKG_ADD from the install directory
(octave-2.1.49 on RedHat 7.3 exhibits this problem).
