An alternative tradition uses a COPYING file. I'm not sure which is older, but most GNU projects use COPYING instead of LICENSE. Meanwhile, some projects use COPYRIGHT or other variation, BSD-style licenses are often added directly to source files, and properly applying LGPLv3 to your project involves adding a separate COPYING.LESSER file. It's a mess.
