# This script searches your srcdir for an egrep style pattern. This can quickly
# help you build a list of the places you need to modify when changing a header
# or other "global" name. The only argument is the pattern you want to search
# for. It should be quoted to escape shell interpretation of the pattern's
# special characters.

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