Conversion of lat-Lon rasters to UTM

[Terry Duell]

Ladies and Gentlemen,
I hope someone can help me.
I have some raster (cell) data files in a lat-lon projection, and would
like to extract relevant sections and convert to UTM and save into an
appropriate UTM mapset.
The problem is that I can't remember how to do this (or even if I have
been able to do so in the past...age has its difficulties!), nor can I
find any GRASS commands which seem to fit the bill.
Any help or advice will be gratefully appreciated.

Cheers,
