[Metakit] FYI, new developments

[Jean-Claude Wippler]

There has been quite some progress on the Vlerq project in the past  
months, which is finally evolving from being a research project to  
producing tangible software.

Vlerq aims to become Metakit's successor one day.  It will remain  
file-format compatible with Metakit as long as possible (though at  
some point new features in Vlerq will need to extend the current file  
format).

If you want to track the progress on this, see

Development and testing are geared towards Tcl right now, but 70% of  
the core code is in C and intended to become usable for other  
languages as well (as well as from pure C).

The main differences with Metakit are:
  - substantially higher performance for many operations
  - scalable well beyond 2 Gb on 64-bit platforms
  - no more attached vs. unattached view dichotomy
  - a completely different "differential" commit model
  - dataflow-capable, i.e. automatic change propagation
Those last two are central to Vlerq, but still some way off.
