THUD 0.25 available

[Thien-Thi Nguyen <ttn@gnuvola.org>]

release notes:

  Yes, development has shifted away from the old openbrick to a machine
  capable of (decently) running Dinotrace.  Text-only green-screen, RIP.
  But wait there's more!  THUD also moved from RCS(!) to Git:

  Lastly, i have resumed using uppercase letters in email.  Wow!

README excerpt:

  THUD is a cycle-oriented scheme-based register transfer level (RTL)
  simulation environment.  The design is expressed in THUD hardware
  description language (HDL), which supports basic 1/0/x operators and
  hierarchical instantiation.  THUD can be used in batch mode or through
  one of its interactive faces.

  Primitives are provided for session management; file format translation;
  scheduling; data structure examination; compilation; HDL generation; and
  of course, simulation.  Additionally, the entire Scheme development
  environment afforded by Guile is present.  The distribution includes a
  small test suite; documentation in Info and HTML formats; and some
  examples.

NEWS excerpt:

  - 0.25 | 2008-02-12

    - License now GPLv3+ (see COPYING)

    - Bugfixes for `dumpvars'

      - Regression

        THUD 0.24 (2004-08-08) broke `dumpvars': Output contained only
        the module declarations and initial dump; the rest was omitted.
        Now fixed.

      - Values only dumped when changed

        Prior versions of THUD (except 0.24) would dump all signals
        requested on all cycles.  Now, it dumps only those signals whose
        values changed between the previous cycle and the current one.
        VCD (Value Change Dump) is the format name, after all.  :-/

    - Enhancements to `dumpvars'
      - Timescale now 1ns
      - Aliases excluded
      - Tested w/ Dinotrace 9.3e

    - New thud command-line option: --out FILE

        When given this option (or "-o FILE" for short), thud adds the
        .th files as usual, then does "compile-to FILE", then exits.
        See examples/lfsr/go, for instance.

    - Maintenance uses GNU Autoconf 2.61
