+I'd like to include this in ikiwiki. Using vim for syntax highlighting is
+suprising to me, but it seems to work great. Would it be possible to
+license it the same as the rest of ikiwiki (GPL) instead of dragging in the
+perl license?
+
+Text::VimColor will need to be added to Debian..
+
+It looks to me like the file parameter is a security hole, since it allows
+inclusion of arbitrary files into the wiki, including ones outside of the
+wiki source tree. I think this option should either be removed, or be
+limited to reading files inside the wiki source tree. If it's retained it
+should also add an appropriate dependency on the included file.
