I really miss the "-rescale nearest" feature that the older texture tool had. 
Any
news on the progress of implementing some of the features the old version had? 
Where
can I find a full pdf with a user guide for nvcompress.exe like we had for 
nvdxt.exe?

This is almost implemented now. The only reason why the bug is not closed is 
because
it has not been tested extensively, and I'm not fully satisfied with the 
complexity
of the resulting code.

The main problem is that the input takes a mipmap pyramid, and when you want the
output to be rescaled, the provided mipmaps can either be ignored and 
regenerated, or
you could try to find the closes mipmap for every rescaled output mipmap. I'm
implementing the latter, and it's a bit of a mess. 

I'd like to revisit the code, try to clean it up, and possibly implement a 
simpler
approach.

Regarding the documentation, there's extensive documentation of the API on the 
wiki at:

http://code.google.com/p/nvidia-texture-tools/wiki/ApiDocumentation

and I'm planning to document the command line tools at:

http://code.google.com/p/nvidia-texture-tools/wiki/CommandLineTools

You can track the progress of the documentation with Issue 20:

Support for scaling is now fully implemented, and reasonably tested. You can 
find the
documentation of the available rescaling options at:
