Converting MS Documents to PDF using LibreOffice

I've been a long time user of LibreOffice. I first started with StarOffice, before moving to OpenOffice, and finally the latest incarnation, LibreOffice. While I use office suites less, preferring Wiki's and if a versioned document is required, LaTeX, I still on occasion receive MS documents. Rather than reading these documents in MS-Word or MS-PowerPoint formats I prefer to convert to a PDF. Here is how to do that. The following shows how to convert a presentation to a PDF. It is a headless operation that works just as well over a set of documents.

loimpress --headless --convert-to pdf presentation.pptx 

Similarly,

lowriter --headless --convert-to pdf document.doc
