specification was too liberal in some areas and missing things in others.

allowing the set of directories searched to be specified either by the
LLVMDO_DIRS env var or by the -dirs "dirs..." command line option.

This is like llvmgrep but instead of running grep, it runs the command
given by the first argument. For example, to find the top ten files with
the most lines in llvm, you could:

utils/llvmdo wc -l | sort -nb | tail

Or, to find any source files with the wrong permissions, you could:

utils/llvmdo ls -l | grep -v rw-r--r--

Hopefully, you get the idea.

replacement for getsrcs.sh which now generates too much text to put on a
Linux command line. The approach taken with llvmgrep is to execute a find
command and execute a grep on each file that matches the name pattern. The
arguments to this script are the same as those of egrep. Note that the -H
and -n options to egrep will always be passed so that you always get the
file and line number of matches.
