Hi Denis,

I have been thinking about the whole thing some more:

With the -N flag to wmk and unfortunately wmk looses the
"make-ability" to figure out if a file has to be re-created.

Ideally, the -o options that can currently be specified in the .wmlrc
file should also be read from .wmkrc so that wmk can base its decision
about recreating a file from this option.

Should I try to implement this in wmk? I guess this could then
"replace" the -N option. 

Question: where should the code to read .wmkrc be moved to?
