 # Whitelist appropriate assets files.
-# Note that you will need to maintain this whitelist yourself if you modify File::$allowed_extensions
+# This file is automatically generated via File.allowed_extensions configuration
+# See AssetAdapter::renderTemplate() for reference.

-# If you are not using Apache then you can ignore this file.
-# If you are using IIS then you should look at assets/web.config instead.

-# To add an extension to the list, you need to put another string of the form "ext|" on the
-# FilesMatch line, inside the parentheses. 
-#
-# For example, to add *.exe files to list of downloadable assets, change this line: 
-#
-#   <FilesMatch "\.(?i:html|htm|xhtml...
-#
-# To this:
-#
-#   <FilesMatch "\.(?i:exe|html|htm|xhtml...

-# Once you do this, visitors will be able to download *.exe files that are uploaded to the assets
-# directory.
