1. information is duplicate. once in POM's dependencies and once in the
 maven.multiproject.includes property.
 2. it works without problems only for projects with relative paths, e.g., from
 one CVS repository.. for projects from multiple SCM repositories it's harder
 to maintain the same relative links on all developer computers.
 not sure the unified source directory structure addresses this issue.
