+
+These are syntax highlighting files for the Emacs and XEmacs editors. Included
+are:
+
+* llvm-mode.el
+
+ Syntax highlighting mode for LLVM assembly files. To use, add this code to
+ your ~/.emacs :
+
+ (setq load-path
+ (cons (expand-file-name "path-to-llvm/utils/emacs") load-path))
+ (require 'llvm-mode)
+
+* tablegen-mode.el
+
+ Syntax highlighting mode for TableGen description files. To use, add this code
+ to your ~/.emacs:
+
+ (setq load-path
+ (cons (expand-file-name "path-to-llvm/utils/emacs") load-path))
+ (require 'tablegen-mode)
+
+
+Note: If you notice missing or incorrect syntax highlighting, please contact
+<llvmbugs [at] cs.uiuc.edu>; if you wish to provide a patch to improve the
+functionality, it will be most appreciated. Thank you.
