  10 # This script finds all the source code files in the source code directories
  11 # (excluding certain things), runs "wc -l" on them to get the number of lines in
  12 # each file and then sums up and prints the total with awk.
  13 #
  14 # The script takes one optional option, -topdir, which specifies the top llvm
  15 # source directory. If it is not specified then the llvm-config tool is
  16 # consulted to find top source dir.
  17 #
  18 # Note that the implementation is based on llvmdo. See that script for more
  19 # details.
