Changes between versions 0.4b24 and 0.4b25 (released ??????????????????)
========================================================================
1. Added a mini howto from Patrick Walsh in the examples
directory.
+2. Minor man pages syntax corrections. Thanks to
+ Chris Danis <screechco@home.com> for reporting the bugs.
+
+3. Added a script from David B. Peterson <dave@toppledwagon.com>
+ to the examples section. It features dumping several
+ filesystems to a remote tape drive upon ssh.
+
+4. Added a patch provided by Richard Jones <rich@annexia.org>
+ which allows BRADEMAX (number of read errors tolerated by
+ dump) to be adjusted using the -I option.
