I've just found out that Gnome Help handles info files in a clickable link way with a heirarchical index down the left-hand side, it's actually quite good! Mind you, first page I tried it on, Gnome Help crashed, same page on the second attempt worked fine. It also does the man pages too. Large man pages are a PITA, e.g. mplayer's pages are hard to find stuff on, so a good info file would probably be more useful. I tend to dislike info too but sometimes man pages just don't cut the mustard either. -- Blast off and strike the evil Bydo empire! http://youtube.com/user/tarcus69 http://www.flickr.com/photos/tarcus/sets/

MPlayer has extensive HTML help too, but I tend to use the man page a lot more and usually manage to find what I want in it. I have had a few years to get used to it though. -- TH * http://www.realh.co.uk

Worked here (Fedora 9) without crashes. I've noted it for future reference. -- martin@ | Martin Gregorie gregorie. | Essex, UK org |
