[GRASS5] v.surf.idw

[Sabine Grabner]

hello,  
 
i need to interpolate my temperature data from a vector file with few stations 
to a raster map. therefore i need to calculate the temperature at any station 
at a reference elevation first, than make the idw-interpolation and bring the 
data to original elevation back again with a temperature lapse rate. 
 
i thought i could do this by manipulating the module v.surf.idw but i can't 
find the module in the source code (downloaded cvs snapshot). i have no 
directory src/vector like src/raster. i found v.surf.rst in 
 
ueberflieger:/opt/grass53sources/grass53_exp_2004_06_12/src/mapdev/v.surf.rst 
#  
 
please tell me where i can find the required module. thanks a lot, sabine
