How do I add a .sty file to my TeXShop installation?
I'm trying to get into LaTeX and have to use a publisher provided cls file (and some tex and bst files) and try to use them with my LaTeX installation. I have the latest version of LaTeX and use texmaker as editor.
I tried to google for advise how to do that but its either confusing or it seems that things changed in lion/2011.
