I'm fairly new to LaTeX so I don't really know much yet.
Is there a way I can make a custom document class that embeds an external document containing custom macros?
For example, I have right now a MyBook.cls file with a few small changes from the default Book document class. I would also like to define a bunch of \newcommand{} macros, but I don't want to have to do it in every custom document class.

\newcommandin amycommands.styormycommands.texfile and then load it using, respectively\usepackage{mycommands}or\input{mycommands.tex}– Guido Dec 11 '12 at 20:30mycustomcmds.sty) that contains several macros you want to use in many different documents that all useMyBook.cls? I think this can be done with\usepackage{mycustomcmds}. But perhaps you have something trickier in mind..? – jon Dec 11 '12 at 20:31\usepackageon my custom list of commands. – agent154 Dec 11 '12 at 20:47
