----- Forwarded message from Werner LEMBERG ----- With permission of Matthias I've just uploaded his bundle of TeX extensions (clasen.tar.bz2) to ftp.dante.de. Note that this stuff is about five years old -- the old ftp address is no longer valid.
I'm not sure where to install since I couldn't find similar stuff; I suggest `systems/extensions/' as the place where to unpack the archive (which creates an additional subdirectory called `clasen').
Below some text for ctan-ann.
======================================================================
This bundle contains some proposals for extensions to TeX which I have implemented in a series of change files. These have only been tested with web2c 7.2 as contained on the TeX live III CD.
glue/glue.ch Adapt Knuth's glue.web to replace all cases of floating-point arithmetic in TeX by fixed-point counterparts.
hyphenation/classes.ch: Implements hyphen classes.
hyphenation/count.ch: Implements demerits for more than 2 consecutive hyphens.
math/accent.ch: Implements nestable and under math accents.
math/cramp.ch: Implements primitives to switch to cramped styles.
math/radical.ch: Implements generalized radicals with a left and right delimiter.
math/fraction.ch: Implements mathstyle and fraction.
hz/hz.ch Implement the hz-algorithm, ie using variants of a font to achieve better justification.
margin/margin.ch Implement marginchar for hanging punctuation and hyphenation and optical margin correction. ----- End forwarded message -----
Thanks for your upload. I installed it in CTAN:/tex-archive/systems/tex-extensions/clasen/
