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