zip file can be produced.

build nickname can be specified with the
  -Dbuild.nickname=somename
and the build version can be specified with
  -Dbuild.version=someversionstring
These will default to development and head-rXXXX where XXXX is the revision
number of the svn checkout or Unknown if the revision number cannot be determined.
Note: This will be extended later.

The buid nickname and build version are placed in the MANIFEST.MF of the dacapo.jar
as Specification-Version and Implementation-Version respectively---this needs to be
checked for sanity.

[svn r536] Introduced hack to get around bug where geronimo only loads org.spache.geronimo.kernel.rmi.RMIClassLoaderSpiImpl
from the jar dacapo jar file.  Also removed the MANIFEST classpath entries that are no longer necessary.

[svn r535] Changed the dacapo.jar cli for daytrader to be loaded relative to the supplied scratch directory.
Removed reduntent main from daytrader Launcher.

that mvn is located in, this enables mvn to run mvn without the external path
having to include mvn.

Disabled (for the moment) stdout digest.

Changed the location from which jasper, jasper-el and
  tomcat are obtained to that of the tomcat tagged
  release 2.1.4 under geronimo
Changed the location that jstl is obtained from to
  the java dev repository since it has been relocated
  from the apache incubator

so changing the checksum to the new correct one.

checkout of jython, which uses a indirection for part of the checkout
to svn.python.org no longer functions correctly.  To address this
the following has been done:
1) The svn checkout task now has a parameter to ignore failure---this is
   not ideal but the checkout of jython will checkout all and timeout
   on the indirection then finally fail.
2) The CPythonLib, which is constructed from python.org source is now
   take from a download of a the 2.5.4 python source package.
3) MD5 checksums have been updated to reflect the changes.
4) Oddly the jython build will fail with three of the source files containing
   a non-ASCII character in the some comments.  While these files comply with
   the python standard by indicating the character encoding to use, they still
   do not build under ubuntu 8.10, but do build under ubuntu 9.04.  A patch
   has been added to jython.patch to change the characters to an approximate
   ASCII equivalent.
