 # This script just prints out the path names for all the source files in LLVM.
+# The optional -topdir option can be used to specify the top LLVM source 
+# directory. Without it, the llvm-config command is consulted to find the
+# top source directory.
 #
 # Note that the implementation is based on llvmdo. See that script for more
 # details.
