I agree! Since the first time I saw the statist help 
text that I perceived the existence of two styles of 
options. I don't know why I chosen the old style for 
the new options. Perhaps because the majority of 
options are in the old style. What a bad criterion!

What about if we turn all options to the new style of 
using "--" for full option name and "-" for 
abbreviations? The old style could still be accepted by 
produce a warning that it is deprecated and will no 
longer be supported in future releases. Only the new 
style would be documented.

You are correct! I simply don't know how to program 
with python, and I didn't know the existence of awk 
until some days ago. That's why I put some tips on the 
usage of awk and other gnu core utils. I discovered 
awk while trying to compile statist under Windows. 
Reading GnuWin32 download page I had interest in 
downloading core utils, and reading core utils 
documentation I found "awk" and "join". I even thought 
about removing recode.c from statist, but I think that 
the syntax of a "recode_config_file" is still simpler 
than the syntax of awk, at least for people who don't 
know how to program in C. Of course the development of 
recode.c wouldn't have been a priority if I already 
knew awk.

I still didn't find a tool for merging databases. I 
tried "join", but the results weren't satisfactory.
Perhaps I don't have enough knowledge on how to use 
join.

Best,

Jakson
