+EXTRAS:

+"extras/coffee-script.js" is a concatenated and compressed version of the 
+CoffeeScript compiler. To use it in the browser, include the script after any 
+inline script tags of type "text/coffeescript" on the page. It will compile
+and evaluate all of the scripts in order.
+
+
+This folder also includes rough cuts of CoffeeScript syntax highlighters for 
+TextMate and Vim. Improvements to their lexing ability are always welcome.
+
+To install the TextMate bundle, drop it into:
+  ~/Library/Application Support/TextMate/Bundles
+
+To install the Vim highlighter, copy "coffee.vim" into the "syntax" directory of
+your vim72, and enable it in either of the following two ways:
+
+  * Manually, by running `:set syntax=coffee`
+  
+  * Or automatically, by creating a "filetype.vim" file within "~/.vim", which
+    contains something along these lines:
+    
+    if exists("did_load_filetypes")
+      finish
+    end
+    augroup filetypedetect
+      au! BufRead,BufNewFile *.coffee setfiletype coffee
+    augroup END
