10# This script searches your srcdir for an egrep style pattern. This can quickly
11# help you build a list of the places you need to modify when changing a header
12# or other "global" name. The only argument is the pattern you want to search
13# for. It should be quoted to escape shell interpretation of the pattern's
14# special characters.
15#
16# Note that the implementation is based on llvmdo. See that script for more
17# details.
