Deleting a file outside a consumer

[Davis, Daniel]

I have an odd case and Google is not helpful because its an odd case
(file producer is always matched).  I need to convert PDFs to SWF on
linux in a route.  The most common tool is called pdf2swf but it has a
problem characteristic, it can only read from a file and not a pipe
because it reads the file twice.  The operations in in the middle of a
bunch of routes kicked off from a JMS message.  It works fine in the
route shown below.  The issue is that I am left with at least one file. 
The camel file consumer does a great job of cleaning up after itself if
one wants.  Who would expect the file consumer to delete the file it had
just written?  I have not found a component that just does OS level file
manipulation without reading or writing (that doesn't mean there isn't
one just that I have not found it).  I could write a component (but the
point of Camel is to not reinvent the wheel unnecessarily) or just call
Java file operations.  I can do command line operations though they
would be platform specific.  I really don't like going around Camel if
there is a way to do something with Camel.  And in the route I already
know the name of the file(s) and I am done with them by the end of the
route.

Does anyone have a suggestion for doing this from XML DSL or Java DSL
without going around Camel?
