[Ifeffit] Tk804.025_beta, update

[Bruce Ravel]

Hi folks,

I just wanted to leave you all with an update as to the issue raised
earlier this week by Joon and Paul regarding the use of perl/Tk
804.025.

This message concerns linux and unix users and OSX users who know how
to build everything from source.  This is not an issue for Windows
users because I have built the executables for the programs using an
version of perl/Tk taht is not effected by the problems I will discuss
below.


The version of perl/Tk currently being distributed at www.cpan.org is
version number 804.025_beta5.  If you go to the CPAN website or use
the CPAN interface to install perl/Tk from the command line, you will
end up downloading that version of perl/Tk.

In response to mail from Joon and Paul, I downloaded and installed
that version of perl/Tk and have come to the conclusion that it is too
unstable to be reliably used with Athena and Artemis.  One of the
problems raised by Joon and Paul was, in fact, my own bug.  However,
there are several other serious problems that are bugs in perl/Tk
804.025 and so are out of my control.

For the foreseeable future, I urge everyone to use an older version of
perl/Tk -- 800.024.  I keep a copy at my web site:
  http://leonardo.phys.washington.edu/~ravel/misc/Tk-800.024.tar.gz

Athena and Artemis are very well tested against this version and
do not require any of the functionality offered by the more recent
version of perl/Tk.

I will keep my eye on the development of perl/Tk and let people know
when I think it is acceptible to upgrade to the more recent version
(which will have some nice features, such as unicode support allowing
e.g. Japanese speakers to keep their project journals in Japanese).

I hope this hasn't been too confusing for anyone and I want to again
thank Joon and Paul for their input as I worked through this issue.
