  12 # (excluding certain things), runs "wc -l" on them to get the number of lines in
  13 # each file and then sums up and prints the total with awk.

  15 # The script takes one optional option, -topdir, which specifies the top llvm
  16 # source directory. If it is not specified then the llvm-config tool is
  17 # consulted to find top source dir.

  19 # Note that the implementation is based on llvmdo. See that script for more
  20 # details.
