When I was experimenting with pdflatex, I started to read about 
different file formats, and I fugured out that, like I need Embedded 
PostScript to embed graphics in PostScript output, I need Embedded PDF 
to embed graphics in PDF output. So I converted my EPS files to EPDF 
with "convert" program from ImageMagick, but I was still getting 
"Unknown graphics extension" error, just like with EPS files, so I gave 
up, thinking that if I don't know how to embed Embedded PDF into PDF, 
than I have to do something completely wrong, and it's not only the 
fault of the file format I use.

Please, maybe I could figure out what I'm doing wrong. Thanks a lot.

But is having different LaTeX source to latex and pdflatex the only way 
to do it? Of course I could pipe my source through "sed 
's/\.eps}/.epdf}/g'" or something like that, and directing the output to 
pdflatex on the fly, but it doesn't look like a very elegant solution. 
Can I write my source file in such a way, that latex and dvips will use 
different files than pdflatex, parsing the same source? Or better yet, 
tell pdflatex to somehow convert EPS to EPDF on the fly? Or am I just 
asking stupid questions?
