Okay, so here's the low-down.

I am using reStructuredText to build PDF documents for the company that I work for. We use RST because of the relative ease with Mercurial versioning compared to OpenOffice documents (not that it would make a difference in this case). This is all well and good, except some of these PDFs need to be editable. I'm 99% sure there's no way to do this with RST, but is there any freeware out there that can let you make editable fields in a PDF that is already built?
