DES 1.8.1 Released

Subject: DES 1.8.1 Released

[Apologies for multiple receptions]

In order to cellebrate the resurgence of Datalog in academia and
industry (Datalog 2.0 workhop, just running now), I would like
to contribute with a modest new release of DES fixing some problems.
So, the new release

  Datalog Educational System version 1.8.1

has been launched on March, 17th, 2010, and ported to

  Ciao Prolog 1.10p5
  GNU Prolog 1.3.1
  SICStus Prolog 3.12.2
  SWI Prolog 5.8.2

The current release is only a bug-fix for binaries, which lacked some
libraries avoiding to generate test cases. Also, whereas these binary
distributions enjoy all the features, consult Section 10 of the user
manual to read the limitations w.r.t. the source distributions.

Release notes are attached to the end of this message.
Please, see for details.

  Best regards.
