[RFC] cgrep, a grep-like tool for C-family languages

Hi,
I would like to explore the possibility of cgrep getting added into
clang-tools-extra.
cgrep is a grep-like tool for C-family source files.
cgrep lets you regex-search through C-family source files for
specific AST nodes. So for example you can search for member function
declarations
that have "[Rr]un" in their name.
Currently Linux and Cygwin builds are supported.
Supported LLVM/Clang versions are 5,6,7,8,9 and 10.
Here's the link:

What do I need to do to be able to move this forward if there is any interest?
