[tex-hyphen] License of hyphenation patterns

[Karl Berry]

More to write about licenses, but for right now:

    ar> with, obviously, the addition of
    the "renamed if modified" clause.

No such "renaming" clause exists in LPPL 1.3.  That was the major change
in 1.3 (see Frank's long long article about it in TUGboat if you want).
What does exist is the slipperier notion of "identification".
Clause 6a is the crucial one:

  a. If a component of this Derived Work can be a direct replacement
     for a component of the Work when that component is used with the
     Base Interpreter, then, wherever this component of the Work
     identifies itself to the user when used interactively with that
     Base Interpreter, the replacement component of this Derived Work
     clearly and unambiguously identifies itself as a modified version
     of this component [...]

For example, if you write a new article.cls, you can name your file
article.cls, and even distribute it under that name (highly highly
disrecommended!!  ... but legal), but according to the license you must
change the \ProvidesClass (and many comments, etc., etc.).
