well, kkrunchy is a small exe packer primarily meant for 64k intros. it's relatively useless for anything else actually, because the depacker was relatively slow in older releases (about 1-2MB per second on my machine) and is dog slow in the newest version (about 90-120k per second for typical data on my p4 2.4GHz). kkrunchy also doesn't try to pack DLLs and can't handle exports or TLS (thread local storage) - as said, it's meant for 64ks.
