Hi Phillip, We are not talking about native English speakers here, but legal language. How a court will decide, depends on many factors. Either way, we can only speculate what will happen and we do not know the true intension of the author. regards Keith. Am 26.10.2011 um 10:49

There's hardly big bucks involved here. If you think you can improve the performance of this package, while retaining its overall structure, then the nicest way to do it is to write a small wrapper package that requires ucharclass and then patches some of its internal macros to work more

O.K. I will jump in here. Intellectual property rights are often a great big gray zone. Maybe, it is time the author of the package speaks up himself what is meant. Also, it does seem clear if the code being used or parts thereof are from a different party, who may or may not have rights which

It's weird Mike hasn't replied yet, but I vaguely remember him saying that he wanted to prevent fragmentation of the package. That being said, the terms of the license don't prohibit you from posting code that modifies the package (going back to a question in Bruno's original post). Nor does it

No, the license of the package in not LPPL. In fact, it is non-free and that is why it is not included in TeXLive. The README in License section says: You may freely use this package, but you are discouraged from modifying this package and then redistributing it. Instead, please contact me

please contact me (ideally on the XeTeX mailing list) and we can discuss the changes you wish to make. If they benefit everyone, they will be worked in as a new version. I would like to invoke that clause. I am definitely not planning to release any modified version of the package.

Yes, firstly because it does not make the software free any more (not just free in price but also free in modification, etc) and secondly LPPL never discourage you from modifying the software. On Sun, Oct 23, 2011 at 8:53 PM, Philip TAYLOR (Webmaster, Ret'd) p.tay...@rhul.ac.uk wrote: Vafa

Hello all, Loading the ucharclasses package with no option is extremely slow ( 2min on my installation), because it loads every Unicode block (as documented). The performance can be significantly improved by using lower-level code for the loops. For instance, using the following helper macro
