Non-bus powered bare schematic

Can someone point to a simple non bus powered schematic? I don't need you to show the outputs, or the sip interface, just the hardware that avr-usb needs to work on external (5v) power. (The chip I have on hand is a atmega324p, but any chip would be fine.)

Is there a tutorial somewhere I'm missing, or do I just have to read the source to PowerSwitch and hope I catch it all?

Wow, I should have previewed that: I mean there's no need to show other outputs the circuit is controlling, or the ISP interface.

PowerSwitch actually IS an externally powered device. In order to circumvent some problems when only one power supply is available, the AVR is ALSO powered from the USB.
