Changes between versions 0.4b23 and 0.4b24 (released ?????????????)
===================================================================
5. Detect the use of incompatible options to dump and
refuse them (like -a and -B options together).
+6. Added bzip2 compression to dump/restore (use option -j level
+ to select it). Note that you will need a restore version
+ >= 0.4b24 in order to restore a bzip2 compressed dump.
+ The same warning as for the zlib compression applies:
+ the tape format of a bzip2 dump is not compatible with the
+ original BSD tape format.
+
Changes between versions 0.4b22 and 0.4b23 (released July 20, 2001)

Need to verify:
---------------
4. Implement a DEBUG option which doesn't fork on each tape, making
it able to debug dump with gdb.
-5. Extend the compression patch to use bzip2.
+5. Make a bootable dump tape? I don't know if it is possible...

a archive_file
Archive file. Archive a dump table-of-contents in
the specified archive_file to be used by
ufsrestore(1M) to determine whether a file is in
the dump file that is being restored.
-8. EA/ACL support in dump (requested by Michael Ju. Tokarev

+9. Dump compiled with RedHat's 7.0 gcc seems to hang for some
people. When compiled with kgcc all the problems disappear.
Will the RedHat's 7.1 gcc resolve this ?
