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