unoconv listener in an automake file?

[Paul Elliott]

unoconv is a program that converts openoffice any other documents to different 
formats. Its man page says it can use a listener: Example:
> unoconv --listener &
> unoconv -f pdf some-document.odt
> unoconv -f doc other-document.odt
> unoconv -f jpg some-image.png
> unoconv -f xsl some-spreadsheet.csv
> kill -15 %-

If the kill is left off, the listener continues even after the make completes
and  if debuild has started the make, it will hang untill someone kills the 
listener. ps -f shows that the listener has made the  ppid=1 after the make 
completes.

unoconv man page says that you can omit creating a listener in which case 
unoconv will create its own. I have never gotten this to work, and it will 
still have the problem of killing the listener afterwards.

In the example, the kill command uses the bash job control concept "%-". Is 
this a legal concept in the concept of a Makefile.am? You would probably have 
to insure that you were in the same shell as the one that started the 
listener.

What is the official, recommended way of handling unoconv listeners in a 
automake file?


Thank You.
