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