11# This script finds all the source code files in the source code directories
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.
14#
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. 
18#
19# Note that the implementation is based on llvmdo. See that script for more
