+;;; Commentary:
+;;
+;; Routines for searching through lists of tags.
+;; There are several groups of tag search routines:
+;;
+;; 1) semantic-brute-find-tag-by-*
+;;    These routines use brute force hierarchical search to scan
+;;    through lists of tags.  They include some parameters
+;;    used for compatibility with the semantic 1.x search routines.
+;;
+;; 1.5) semantic-brute-find-first-tag-by-*
+;;    Like 1, except seraching stops on the first match for the given
+;;    information.
+;;
+;; 2) semantic-find-tag-by-*
+;;    These prefered search routines attempt to scan through lists
+;;    in an intelligent way based on questions asked.
+;;
+;; 3) semantic-find-*-overlay
+;;    These routines use overlays to return tags based on a buffer position.
+;;
+;; 4) ...
