Tutorial for emp package

Question

I really like the idea of the emp package - you write your MetaPost sources directly in LaTeX source. However, I can't make this package work. I read the official readme, but to no avail. Some of my problems:

• Should every emp command go inside an empfile environment?
• Should I have one big empfile environment that contains all of my TeX source? (If yes, then it's terribly ugly!)
• Why am I mixing TeX code and MetaPost code inside emp* environments?
• Do I have to put emp environment inside a figure environment?
• Can I have multiple unnamed empfile environments?

In other words: How does this thing work?

Answer 1

I suggest you to look also at the more recent packages mpgraphics and gmp (I'm the author of the latter), as emp looks not to have been maintained for a long time.

Both package do what emp is able to do, and much more.
