;;; Commentary:
;;
;; Implement the symref tool API using project-files and
;; xref-matches-in-files, which in turn use grep or more efficient
;; tools if available.
;;
;; This is basically a replacement for the symref GREP tool, as a new
;; lowest-common-denominator which works without indices or
;; project-specific configuration. It has better performance than the
;; GREP tool because project-files provides a narrower set of files to
;; search, and xref-matches-in-files is highly efficient.
