>The only format you can include while compiling with latex is Encapsulated PostScript (EPS). If you are compiling with pdflatex to produce a PDF, you have a wider choice. You can insert:
- JPG
- PNG
- PDF
- EPS
Wow, that's the widest choice I ever had!
//well, I've only pngs and jpgs, so I'm ok with that <_<
//pdf into pdf? they tempt me to make a recursive paper ~_~
