Many thanks for checking.

csl-based reduce, and csl, are really strange. reduce is a compiled binary, and 
it needs to have reduce.img *in the same directory* (same for csl). Both of 
them also want to see reduce.doc and reduce.fonts also in the same directory, 
if they are started in the gui mode (in the command-line mode reduce.fonts and 
reduce.doc are not needed). So, all these files and directories should be 
together somewhere. And not in /usr/share, because reduce is a binary, and 
reduce.img is also processor-dependent, as far as I know. So, I choose 
/usr/lib/reduce; do you have better suggestions? Should it be 
/usr/lib64/reduce on amd64?

Moreover, symlinking /usr/lib/reduce -> /usr/bin/redcsl does not work: the 
program tries to find reduce.img in /usr/bin, and fails. The only way I've 
found is a 2-line script in /usr/bin which execs /usr/lib/reduce/reduce.

Thanks again,
Andrey
