 # Simple script to update the version of DTC carried by the Linux kernel
 #
 # This script assumes that the dtc and the linux git trees are in the
 # same directory. After building dtc in the dtc directory, it copies the
-# source files and generated source files into the scripts/dtc directory
+# source files and generated source file(s) into the scripts/dtc directory
 # in the kernel and creates a git commit updating them to the new
 # version.
