+    The mp-utils package includes a set of portable Unix utilities written by
+    me, Mid Favila. They attempt to comply with both the latest POSIX and SUS
+    specifications, whilst also implementing de facto standards such as sed's
+    -i option. The only time POSIX and SUS will not be obeyed is when doing
+    so requires relatively useless features to be implemented (that, or they
+    will be #ifdef'd).
+
+    They can be thought of as sitting somewhere between the Suckless tools and
+    Busybox - more sophisticated than Suckless' offerings, and less bloated
+    than Busybox.
+
+    I recommend compiling these statically.
