class="gmail_default">The UK hyphenations patterns must stay
within TeXlive, that's a given. So let's change the license
on the pattern files. As co-creator of the file, I hereby
agree with the MIT license. I don't know if Graham Toal, the
person who worked with me on producing these patterns, can be
reached. I'll try. I am certain it was Graham's intention,
like mine, that these patterns should always be freely
available to everyone.<br>

Having read the MIT licence [1], I feel that it is incompatible with
the intentionally-immutable nature of hyphenation patterns for TeX,
since it explicitly allows modification and subsequent
re-distribution without requiring a concomitant renaming :<br>

However, there is a licence which is ideal for this purpose and
which is, by definition, acceptable within the TeX community, coming
as it does from none less than Don Knuth himself : it is the
licence of tex.web —<br>
<br>
<blockquote type="cite">
<pre>% This program is copyright (C) 1982 by D. E. Knuth; all rights are reserved.
% Copying of this file is authorized only if (1) you are D. E. Knuth, or if
% (2) you make absolutely no changes to your copy. (The WEB system provides
% for alterations via an auxiliary file; the master file should stay intact.)
% See Appendix H of the WEB manual for hints on how to install this program.
% And see Appendix A of the TRIP manual for details about how to validate it.</pre>
</blockquote>
<br>
I therefore propose that we use Knuth's licence, appropriate
modified in terms of name and date and omitting all words after "(2)
you make absolutely no changes to your copy". Thus the licence
might read :<br>
<br>
<blockquote type="cite">
<pre>% This data is copyright (C) YYYY by the TeX hyphenation team; all rights are reserved.
% Copying of this file is authorized only if (1) you are a member of the TeX hyphenation team, or if

If the Debian authorities choose to rule that tex.web can no longer
be included in Debian distributions, then the accompanying loss of
the British English hyphenation patterns will be of zero concern.<br>
