     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.

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