How to use:
Take your FEditor formatted animation and drop it onto AA.exe:
When it's done it will create a "[name] Installer.event" file. It's a big file but the only thing you care about is at the top:
AnimTableEntry(0x0) //CHANGE THIS TO THE SLOT YOU ARE REPLACING
Pretty self explanatory, change the 0x0 to the index of whatever animation you're replacing.
Then open up "Master Animation Installer.txt" and add the generated installer to the bottom.
Include "Master Animation Installer.txt" in your ROM Buildfile (or just put ORG [somewhere in free space] at the top) and the animation will be inserted the next time you assemble with EA!
