Making footprints and schematic symbols are some of the more onerous parts of using Eagle. But most ICs are pretty similar: they're either DIPs, some type of leaded SMD, or BGAs. So I made a Perl library that lets me enter a simple text description of a chip and it will generate a footprint and symbol for me and link them together into a complete device.
