# OVERVIEW

# Header Symbol Index Generator

# DESCRIPTION
#
# This is a static source analyzer that lets us configure Emacs
# keybindings to insert #include lines.

# EXAMPLES

# (defun jart-add-include ()
# (interactive)

# (search (thing-at-point 'symbol))
# (buffer (find-file-noselect (format "%s/%s"
# (locate-dominating-file
# (buffer-name) tag-file)
# tag-file)))
# (header (with-current-buffer buffer

# (goto-char 0)
# (when (re-search-forward
# (concat "\177" search "\001") nil t)
# (when (re-search-backward "\f\n\\([^,]*\\)," nil t)
# (match-string 1)))))))
# (when header
