Each product zips's root should be a single directory with the product name and version to make it handier to unzip

Currently, for example the optaplanner zip, has in it's root 4 directories (binaries, examples, sources, webexamples). So if you unzip this into ~/tmp/ with already 2 dirs (bar, foo), you get in ~/tmp a clutter of 6 dirs:
~/tmp
~/tmp/bar // Not part of BRMS
~/tmp/binaries
~/tmp/examples
~/tmp/foo // Not part of BRMS
~/tmp/sources
~/tmp/webexamples

In the maven assembly, simply add this 1 liner:
<includeBaseDirectory>true</includeBaseDirectory>

And you get:
~/tmp
~/tmp/bar
~/tmp/foo
~/tmp/jboss-bpms-brms-6.0.0-redhat-5-optaplanner/
~/tmp/jboss-bpms-brms-6.0.0-redhat-5-optaplanner/binaries
~/tmp/jboss-bpms-brms-6.0.0-redhat-5-optaplanner/examples
~/tmp/jboss-bpms-brms-6.0.0-redhat-5-optaplanner/sources
~/tmp/jboss-bpms-brms-6.0.0-redhat-5-optaplanner/webexamples

Much handier.
