+cgo: collection of generic optimizers
+
+!!!  HOW TO INSTALL  !!!
+
+Running `sudo make install` (or your flavour of privilege elevation) at project root
+places library/header/executable files in /usr/local. The program may then be
+launched using `cgo` in any shell, or its functions may be included in your project by
+linking against `cgo` (-lcgo for gcc) and including its headers (e.g. <cgo/de.h>).
+
+`sudo make install-lib` only does the library/header portion of this and skips the binary.
+`sudo make install-bin` only installs the binary.
