+;;; Commentary:
+;;
+;; This file provides a major mode for editing X resource database
+;; files.  It includes font-lock definitions and commands for
+;; controlling indentation, re-indenting by subdivisions, and loading
+;; and merging into the the resource database.
+;;
+;; To use, put the following in your .emacs:
+;;
+;; (autoload 'xrdb-mode "xrdb-mode" "Mode for editing X resource files" t)
+;;
+;; You may also want something like:
+;;
+;; (setq auto-mode-alist
+;;       (append '(("\\.Xdefaults$"    . xrdb-mode)
+;;                 ("\\.Xenvironment$" . xrdb-mode)
+;;                 ("\\.Xresources$"   . xrdb-mode)
+;;                 ("*.\\.ad$"         . xrdb-mode)
+;;                 )
+;;               auto-mode-alist))

+;; The database merge feature was inspired by Joel N. Weber II.

+This variable controls how much of the buffer is searched to find a

+defined by this variable is scanned for the first `:' character on the
+line, and this character's column is the line's goal column.  The
+rightmost line goal column in the region is taken as the region's goal
+column.
+
+This variable can take one of the following symbol values:
+
+ `buffer'    - All lines in the buffer are scanned.  This is the
+               slowest option.
+
+ `paragraph' - All lines in the paragraph are scanned.  Paragraphs
+               are delimited by blank lines, comment lines, and page
+               delimiters.
+
+ `page'      - All lines in the page are scanned.  Pages are delimited
+               with `page-delimiter', usually ^L (control-L).
+
+ `line'      - Only the previous non-comment line is scanned.  This is
+               the fastest method.
+
+This variable is used by the various indentation commands, and can be
+overridden in those commands by using \\[universal-argument]."
