daytrader to build and execute.

1) Build each benchmark regardless of the failure of any other benchmark to build.
2) Report the PASS or FAIL status of each benchmark during the build in a
     log/YYYYMMDD-HHMM/status.txt
   file where YYYYMMDD-HHMM is the time at which the build was run
3) Report the PASS state of a build (i.e. all benchmark built) by constructing a file
     log/YYYYMMDD-HHMM/pass.txt
   (for the same time as in point (1) ).
4) Report the FAIL state of a build (i.e. one or more benchmarks did not
   build correctly by constructing a file
     log/YYYYDDMM-HHMM/fail.txt
   (for the same time as in point (1) ).
Note: Either a pass.txt or a fail.txt file is constructed, not both.

[svn r483] Changed over to using littleG for tradebeans and tradesoap.  The build process is functional,
needs some alteration to make it more elegant.

character sets.  Recomputed affected MD5 sums.

Added in failonerror for cvs checkout failure.
Added in failonerror for svn checkout failure.

files for svn or cvs checkouts so that jar/tar/zip timestamp and
internal value changes are ignored.

Computed new checksums for affected MD5 entries.

differences are identified.

including the meta-data subdirectories in the tar ball and additionally they
force the file date to be constant to ensure a consistent tar ball.

Downloads of source files, svn or cvs repositories now work as follows:
1) if no MD5 checksum exists
     the file(s) are downloaded (and tarred)
     an MD5 checksum is generated
   else
     if the file(s) checksum does not match the existing checksum then
       the file(s) are downloaded (and tarred)
       and the existing checksum is verified to ensure correct behaviour

Added MD5 checksums for the additional downloads for geronimo (activemq, catalina,
jasper and jasper-el).  Updated existing MD5 checksums affected by the changed
tar ball generation.

Updated a couple of MD5 that seemed to apply to earlier versions.

Turned on failonerror and failifexecutionfails for installing activemq, tomcat,
jasper and jasper-el for daytrader.

[svn r477] Added note to indicate that Tomcat and Xalan do not build with Java 6, see bug #2814921, #2814917

[svn r462] Fixed up some platform-specific issues; however require user to have correct mvn in path before calling ant
