[texhax] letterspaceadjust package

[Arno Trautmann]

Hi all,

after giving a talk at the recent DANTE meeting in Hannover, I made a 
small package that might help improve typesetting in very narrow columns 
using LuaLaTeX.
The packages code inserts a small amount of stretchable space between 
all glyphs (not only words) and in combination with the microtype 
package results often in a more even, less spaced-out typesetting. As 
the whole this is quite experimental, I'd be very happy to have some 
alpha-testers who would check the code and see how stable everything is 
in everyday usage.
The package and documentation is available at:

https://github.com/alt/letterspaceadjust

I would be very thankful for any testing, comments and suggestions, and 
hope that a stable version of this package could increase the quality of 
narrow column typesetting a bit.

The original idea and a large part of the implementation of the code 
came from Paul Isambert:
