Comment (by hamish):

 v.univar too,

 {{{
 g.copy vect=archsites,tmp_arch
 v.db.addcol tmp_arch column='x double, y double'
 v.to.db tmp_arch option=coor columns=x,y

 eval `v.univar -g tmp_arch column=x type=point | grep -w mean`
 X_MEAN=$mean

 eval `v.univar -g tmp_arch column=y type=point | grep -w mean`
 Y_MEAN=$mean

 echo "Center of point cloud: $X_MEAN, $Y_MEAN"
 }}}

 Center of point cloud: 598326, 4.92146e+06

 would be nice for y coord to be intact (ie preserve 3 digits to the right
 of the decimal point (mm))
