The aPE is a patcher program that can be used to patch packed/protected executable files. This is done by code insertion in packer/protector code so that the program can be patched normaly without the unpacking of the packed file. This means that you can now make smaller patches for packed executables. There is no more need for distribution of larger unpacked files... The aPE can patch them while they are still packed!
The complete list of the supported packers and their options can be found here. Curently there are 83 supported packers, and every packer has it`s own patching procedure. There is also a generic inline patching method that can patch many packers/crypters/protectors.
