wiggle is A utility that applies conflicted patches intelligently. When 'patch' fails, wiggle often can succeed by ignoring changes to the original file that are not relevant to the patch. The result should always be reviewed, as wiggle cannot notice semantic changes that are important.
musl is a new implementation of the standard library for Linux-based systems. It is lightweight, fast, simple, free, and strives to be correct in the sense of standards-conformance and safety. It includes a wrapper for building programs against musl in place of the system standard library (e.g. glibc), making it possible to immediately evaluate the library and build compact statically linked binaries with it.
