Acrobat Distiller used to have a setting for watching a folder. If a
.ps file was saved to that folder, and the distiller program was
running, it would automatically distill the .ps file to a PDF. This was
very handy for mass-distilling large numbers of PDFs, for example,
generating PDFs for the separate chapters in numerous FrameMaker books.
This feature is still mentioned in Acrobat 7 help, but does not seem to
be in the Acrobat 7 Distiller product. Has it fallen by the wayside?
