[GRASS5] Re: license issues

[Markus Neteler]

Hi all!

It seems we can proceed quickly here on the license issue
(and we should!):

Good idea. I start today.

>        - Replace code for the math routines.
O.k. this is more work. Suggestion:
 - move critical modules to src.license_problem
 - replace critical library routines in a second step
   As this are only a few this may not be such urgent.

>        - Replace LZW with a better compression
Suggestion:
- Step1
 Replace the critical file
  src/libes/gis/lzw.c
 with another routine but *identical* funtion headers.
 This is not a nice programming habit, but can be done rather
 quickly. Then publish again to remove critical source code
 from internet.
- Step2
 Replace the LZW-stuff totally. Needs more work.

Should be possible.

Bill, Helena? Do you remember those CERL people? Did CERL have
contracts which might be valid?
 
Best regards
