It is lovely to use:

# Like grep -r except…
# * you can leave off the directory and it will use . instead of waiting like
# a dumbshit for STDIN
# * It handles paths with spaces and quotes.
# * it will not traverse into these directories or files.

It’s designed to replace most of grep’s usecases.
It can search recursively in source code files, skipping directories like .svn.

You’ll never need to hack grep scripts again
