Oops, I mean STDERR

Ok

Cool, works fine nows ;-)

Well the main idea is to log all steps of a long upgrade like e.g. KDE-Base 
as it depends of "[IUR] Xorg 7.2-r5 (KDE-Libs)" while only 7.2-r2 is 
installed and for which right now there isn't yet binaries available.
So colors, in this case, are bad as they make reading of logs more 
difficult.
e.g.
[snip]
^[[1;30mGetRecipe:^[[0m ^[[36mTrying to 
get /Files/Compile/Recipes/LibDRM/2.3.0-r1^[[0m
[snip]

(but could be easily cleanup ;-))

That said, it would be cool if Freshen itself would have this loging option 
builtin (like sam or smitty), isn't it?

Tx again,
