# generate N+1 files named $filename.part.{0,1,...N}.
#
# $filename.part.N will contain the module initialization stuff from the
# of the source file; the other files will contain a module each. Any stuff
# before the first module will be in $filename.part.0.

# Since divide can take a long time, it prints messages saying which part
