USAGE:
 ${0} sourceFolder destinationFolder
 ${0} -s "/exact/path/to/source/Folder" destinationFolder
 
DESCRIPTION:
 This script modifies Doris Result Files (*.res) and Doris Input Files
 (*.drs) by changing locations of the output files to their current locations. 
 It is a mere string replacement utility. It does not check for errors.
 Each modified file is backed up with a .bck suffix (i.e *.res.bck) 
 
 -s: option is used to update *.res files that are already moved to their
     destination, i.e. scp'ed from a different computer. With this option
     ${0} only tries to update files without actually moving anything. 
 
EXAMPLES:
 ${0} -s '/data/batu/adore_MexicoCity2/process/3DKalman/i12s' '/home/bosmanoglu/des3/kalman/3D/data'
