My experiences with Makefiles are different. I can understand mine up to 3 months after I write them. And if I read someone else's Makefile, it's a binary blob, full of hacks, optimalizations, walkarounds and compatibility quirks between GNU make, BSD make, with sometimes different Makefiles for FreeBSD, Linux, OpenBSD, DOS, and Visual Studio uses its own project file in the win32 directory. It's a mess.
