  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.
