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://.
