why examples isn't populated

[Benson Margulies]

from distribution/src/main/assembly/bin.xml, this won't put anything
into examples except bin.

  <fileSet>
      <directory>../examples/bin</directory>
      <outputDirectory>examples/bin</outputDirectory>
      <fileMode>0755</fileMode>
      <excludes>
        <exclude>work</exclude>
        <exclude>work/**</exclude>
      </excludes>
    </fileSet>
