Not a problem -- is there CVS for the wiki manuals? it would make it easy to pick up on changes
There is a history of changes in the wiki of every page, there is no CVS or other versioning system.
right now i'm going to have do it manually nothing seems to be able to bring it down cleanly adobe distiller firefox plugin or any of the usual cmd line programs.
I suggest you first contact admin[AT]contribs[DOT]org as you will most certainly be banned by the protection system that is in place to prevent mass download stuff in order to keep the site available to everyone and I do not think you really want that. Furthermore I doubt if they would encourage the maintenance of manuals in PDF or any other format other than the wiki as the wiki is a pretty suitable to the desires I think.
Is there another source for the manuals other than the wiki page html from the web?
No, as the goal of the wiki was to have all relevant stuff in one place, with the possibility to easily make changes (by lots of people) and additions without having to regenerate documentation, something you are trying to implement again. Having to keep up-to-date has proven to be hard in the past resulting in outdated and invalid information being in the manuals.
May I ask what is the reason to (re)generate documentation in an other form, does the wiki not suit your needs?
