[Tex/LaTex] How to get documentation for the LaTeX letter class

document-classesdocumentationtexdoc

I am trying out TeX and writing some correspondence in it just to learn the basic commands. For the "letter" document class, I have found this reference site:

http://en.wikibooks.org/wiki/LaTeX/Letters

My question, put simply, is as follows:

  • How do I get documentation* on a particular document class, in this case: "letter"?

(*) By documentation I mean: "list of all commands, their syntax and usage"

Note: I can use

texdoc "packagename"

for packages but I don't know how to do the same for document classes?

Bonus/optional complement to this question (feel free to disregard it if you dislike multiple questions in a single post): where do I get a list of document classes from? (I get my list of packages from: http://ctan.org/pkg)

Best Answer

texdoc letter

If you still need more information you can try 

texdoc -l letter

Which gives you a longer list of related documentation. Even more can be obtained by typing 

texdoc -s letter

You will get any documentation with a "letter" somewhere in the name or description with the latter.

Depending on the country your're in other non-standard letter classes fit much better. In Europe for instance I would recommend scrlttr2

Edit (added from comment): there are differences between the unix based texdoc and MiKTeXs texdoc. In MiKTeX texdoc Option -s is not working.
