What command-line options are available in Adobe Acrobat (not Reader) for modifying documents (Convert, Merge, etc.)?

See title. I'd like to convert a bunch of XML files to PDF using Adobe Acrobat (9.0).

Currently, I'm opening each of these files with IE and then convert them manually using the Acrobat Plugin.

I'm curious if this can be achieved without loading each of the files by hand since the generation of the PDFs is a part of an otherwise automated process.

No, there are no command line parameters for Acrobat for conversion. The only command line parameters that exist are the same for Reader or for Acrobat to open a file or to print a file. They are essentially undocumented and they are unsupported but you can see them here. You will have to look at other PDF applications for this functionality.

Another possibility is that if you have Acrobat installed and you can find an application that will open the XML files and has command line parameters for printing, then you can automate it through the XML application by printing to PDF from that application. That's another avenue you might try to find.
