*   Ant naming conventions:
*   - regardless of the actual OS platform,'/' is the directory separator
*     (Ant will convert as appropriate).
*   - multi-word properties use periods '.'
*     - properties ending in .jar define jarfile names only (no path)
*     - properties ending in .lib are fully qualified jars (path and filename)
*     - properties ending in .dir are directory paths
*     - properties ending in .path are path refid names (classpath fragments)
*   - multi-word targets use hyphens '-'
*     - targets beginning with test- are reserved for high level test targets,
*       and are used in test results parsing
*     - targets typically use the form <action>-<object>-<type> (ie. package-bundle-zip)
*   - multi-word macros use underscores '_'
*   - multi-word macro attributes are concatenated
*     e.g. 'runpathref'
*   - multi-word tasks (taskdef) names are concatenated
*     e.g. 'validateconnection'
*   - OS environment variables are in ALLCAPS and have 'env' as a prefix
*     e.g. ${env.XXX}.
*   - Ant properties are lower case.

  This buildfile looks for a eclipselink.jar file in the current directory, and
  generates an appropriate ear file for use as a WLS shared library. If the jar
  does not exist, an attempt to generate one will be attempted (it is assumed
  that the this file resides at the same location as the primary buildfile for
  EclipseLink - not necessary, but assumed).
