Marshall Schor updated UIMA-2970:
---------------------------------

    Description: 
Take advantage of the existence of the Apache dist.apache.org SVN site used for 
releases to reduce the release work for new versions of existing update 
subsites.

A subsite is typically a collection of features and plugins, at various 
"versions", plus metadata that catalogs these items in two files: contents.jar 
and artifacts.jar.  The subsite also has pack.gz versions of the plugin Jars, 
and checksums and signatures for the Jars and pack.gz things.

With each new version, the old versions of the features and plugins do not 
change; just new versions are added and the metadata files are updated; all new 
and changed files get new checksums/signatures.

Change the build process to:
  a) checkout the existing subsite
  b) build just the new versions
  c) compute the new metadata and use the "append" facility to add to the 
existing metadata
  d) allow "committing" just the new/changed files to the dist repo after the 
vote passes.

Since the update site build process no longer has any need of information about 
previous versions, change the update-site organization and POM to have less 
special updates needed (previously, it needed lists of previous versions, etc), 
and make it align with the conventional way other projects are built, where 
possible.
