llvm-mirror/utils/llvmgrep
Reid Spencer a11dd3baf9 Allow a sequence of digits at the end of the directory name when trying to
determine the top directory. This allows the tool to find the correct top
directory when you have something like:

   /x/llvm
   /x/llvm2
   /x/llvm3

Previously the scripts would always find /x/llvm even if you were in the
llvm2 or llvm3 directory because the pattern didn't allow the digits at
the end of the path.

# This script searches your srcdir for an egrep style pattern. This can quickly
# help you build a list of the places you need to modify when changing a header
# or other "global" name. The only argument is the pattern you want to search
# for. It should be quoted to escape shell interpretation of the pattern's
# special characters.

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