It's been awhile since I've written a help file for my apps but I find the need once again. 10-12 years ago there were free programs out there to generate help files but a google search today returned nothing of the free sort. Does anyone know of a decent free help file generator/creator/writer out there these days? If not I can always create a pdf ... but it would be nice to have integrated contextual and general help.

TIA,
Ken
