 # Script to join ppm files
-# Last updated August 24, 2012 by Sasha Philippov, modified from joinvtk script. 
+# Last updated August 24, 2012 by Sasha Philippov
 
 # Usage is, e.g.,
-# joinppm.sh -i FP -o comb/FPc -f 1:4 -p 16 -s d.ppm -x 8 -y 2
+# joinppm.sh -i FP -o comb/FPc -f 1:4 -p 16 -s d.ppm -x 2 -y 2
 
 # That will take the d.ppm files from the id*/ sub-directories of the current
-# directory and put the output (changing the filename from FP*.d.ppm to FPc*.d.ppm
+# directory and put the output (changing the filename from FP*.ppm to FPc*.ppm
 # so you don't confuse the two) in the sub-directory comb (which it will
-# create, if necessary).
+# create, if necessary). -x and -y specify the mpi decomposition of the
+#computational domain. See also below.
