Hi pcman,

as you may be aware, the #lubuntu channel has a ubot in and I can ask for factoids to be added (so that people can issue, say, !grub2 on the channel and it give a link to where to find out more information). 
Issuing the request !pcmanfm reports back (07:25:57) ubot5: Sorry, I don't know anything about 'pcmanfm' Is there an information page (or even two) that have both what it does and information on it's usage? If there is not, or you'd like me to attempt to pull the information on to https://wiki.ubuntu.com/Lubuntu/DocumentationHelp then I'd be happy to do so. I'd also like to link from the lubuntu help page, but do not want to duplicate documentation that is already there and is being kept up to date.
