ComancheNG is an effort to clean up comanche and take a minimalist
approach to the distribution.  In this version 1.0, some things from the
original comanche have been left out, and the services framework has
been extensively reworked.  For example, the class ComancheListener now
replaces the deprecated ConnectionHandler.  The protocol for creating
and using services in now much cleaner.  However, not much has changed
in the core HTTP protocol implementation in this release.  For creating
your own ComancheNG services, see the class comments in ComancheService
and its subclasses.

Also:

The "SBComanche" package adds a nice Star Browser based user interface
for managing ComancheNG services.  And, the "SeasideService" package
implements an interface between Seaside2 and ComancheNG.
