+;;
+;; Features:
+;;   * autocompletion of the language contructions
+;;     such as if, for, foreach, etc blocks,
+;;
+;;   * autocompletion of classes, interfaces and functions
+;;     definitions
+;;
+;;   * autocompletion of the paired symbols, like [], (), "",''
+;;
+;;
+;; Usage:
+;;   Nothing magical, just place the file in a directory where
+;;   Emacs can find it, and write
+;;
+;;   (require 'php-electric)
+;;
+;;   in your configuration files ~/.emacs or wherever you keep it.
+;;   Then you can switch on/off the mode by the following command
+;;
+;;   M-x php-electric-mode <RET>
+;;
+;;   If you like to have it switched on automatically, you should
+;;   put the command in your php-mode hook or create new one,
+;;   like that
+;;
+;;   (add-hook 'php-mode-hook '(lambda () (php-electric-mode)))
+;;
+;;   That's it.

+;;; 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.

+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]."
