# highlight versions 2 and 3 have different commandline options. Specifically,

-# On CentOS 6.2 (using highlight from EPEL), when highlight doesn't know about
-# an EXTENSION, it outputs a lua error and _no_ text, even when the --force

-# This workaround can be removed when the bug is fixed upstream and the new
-# version is packaged in most distributions.

-# The workaround is to set the extension to 'txt' (plain text) when highlight
-# exits with an error (doesn't know the format).
