'''The Third Manifesto''' website [http://www.thethirdmanifesto.com/] lists TclRAL as:
    :   an implementation of the relational algebra concepts in TTM as an extension of the Tcl language. It does not attempt to mimic the syntax of Tutorial D, but does implement a complete set of relational operations in a manner that is adapted to the Tcl programming environment.
Since many of the systems listed are described as not quite complete, TclRAL seems to do Very Good in an area of heavy duty computer science.

I recently released Version 0.8 of TclRAL and thought that now was an appropriate time
to make this page a bit more active for anyone that may be interested in the extension
and wish to ask questions or post examples.

Version 0.8 is a complete rewrite of the extension to improve the code base and lay in
a more maintainable structure. The major new feature of 0.8 is referential integrity checking.
My current vision for the future is (roughly):
   * Additional code rework and testing.
   * Adding a few new features.
   * Honing the command interfaces leading up to a 0.9 release.
   * At Version 0.9, freezing the command interface for longer term backward compatibility support.
   * Leading to a Version 1.0 release.

I won't be so bold as to state a time frame for all of this, but as I use the extension myself
I am as anxious to see it improve as anyone.

Released Version 0.8.1. This version is script compatible with 0.8 and includes some new commands and command
options. Most notable is the ability to trace relvars in much the same manner that one can trace ordinary
Tcl variables.
