##
# Override this method in your uploader to provide a black list of extensions which
# are prohibited to be uploaded. Compares the file's extension case insensitive.
# Furthermore, not only strings but Regexp are allowed as well.
#
# When using a Regexp in the black list, `\A` and `\z` are automatically added to
# the Regexp expression, also case insensitive.
#
# === Returns
# [NilClass, Array[String,Regexp]] a black list of extensions which are prohibited to be uploaded
#
# === Examples
#
# def extension_black_list
# %w(swf tiff)
# end
#
# Basically the same, but using a Regexp:
#
# def extension_black_list
# [/swf/, 'tiff']
# end
#
def extension_black_list; end
