There isn't really a way to go FM -> Wiki, i.e. there are no tools to do so easily. You could dump out HTML from FM and just put them in the wiki but that won't get you the wiki-goodness. We were able to largely automate the process for our first foray but it was simply an ideal candidate because the original content was largely uniform and the end product wiki was template based. I'll summarize below.
We had a book that doc'd commands (roughly 15000 of them) for a scripting language we use internally for our software. These commands were in a tabular format. There were of course some paragraphs that came before the commands in a section, describing their purpose or use, and there were several chapters that were simply explanatory text. Nothing complex. We dumped this stuff out to text files. Wrote a PERL script to identify the various components and modify the text files. We then wrote another PERL script to convert that data to include the wiki template information. We then populated the wiki and made many manual changes. In total, the project took about 4 weeks including planning, which included deciding which wiki format we needed. So, this is possible but that strictly depends on your content, and it will require extra knowledge on your end. Hope that helps. Will. -- Will.
