;;; Synched up with: Not in FSF

;;; Commentary:

;; This file provides support for Cyrillic lettering in footnote mode.
;; It requires an Emacs or XEmacs with MULE internationalization.

;;; Change Log:

;; Apr-05-1997:	Replicate letters when footnote numbers hit the end of
;;		the alphabet.
;; Apr-18-1997:	Added regexp to the footnote style alist.

;;; Code:

Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
