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
