Hawron is a GUI tool for the Apache XML Web Development Framework Cocoon and pure Java. It mainly supports the "Offline Generation Part" of Cocoon, but an embedded Servlet Container (Jetty) for Cocoon's default environment is included. Hawron tries to help Cocoon users with some extra features like publishing offline generated files (ftp, sftp) and editing content (embedded OpenOffice).
