Maciek,
I just had a moment to check on r.in.arc and it is already in the GRASS
5.7
menus (25 Nov. release), under file>import>raster>ESRI Arc/Info ASCII grid
Apparently somebody added it without letting the others know? Abyway in my
grass57_exp_2004_11_13 it isn't there.
Maciek
P.S.
this message was supposed to go here
by mistake I sent it to grasslist@baylor.edu first
sorry for that mess
