;;; Commentary:
;;
;; This program was started by Eric Ludlam, and Joakim Verona finished
;; the implementation by adding searches and fixing bugs.
;;
;; Read in custom-created ebrowse BROWSE files into a semanticdb back
;; end.
;;
;; Add these databases to the 'system' search.
;; Possibly use ebrowse for local parsing too.
;;
;; When real details are needed out of the tag system from ebrowse,
;; we will need to delve into the originating source and parse those
;; files the usual way.
;;
;; COMMANDS:
;; `semanticdb-create-ebrowse-database' - Call EBROWSE to create a
;;       system database for some directory.  In general, use this for
;;       system libraries, such as /usr/include, or include directories
;;       large software projects.
;;       Customize `semanticdb-ebrowse-file-match' to make sure the correct
;;       file extensions are matched.
;;
;; `semanticdb-load-ebrowse-caches' - Load all the EBROWSE caches from
;;       your semanticdb system database directory.  Once they are
;;       loaded, they become searchable as omnipotent databases for
;;       all C++ files.  This is called automatically by semantic-load.
;;       Call it a second time to refresh the Emacs DB with the file.
