Subject cvs commit: cocoon-2.1/src/blocks/linotype/samples sitemap.source.xmap sourceflow.js
Date Sun, 27 Jul 2003 13:13:10 GMT

  Added:       src/blocks/linotype/java/org/apache/cocoon/components
                        SourceRepository.java
               src/blocks/linotype/samples sitemap.source.xmap
                        sourceflow.js
  Log:
  Started a (small) Linotype refactoring to make it source-oriented. When
  finished (it's almost working but still requires some tweaking) it will
  be possible to use Linotype with every (ModifiableTraversable) source
  as a repository - think file://, cvs:// or webdav://.
