+      dylibbundler is a small command-line programs that aims to make bundling
+      .dylibs as easy as possible. It automatically determines which dylibs are
+      needed by your program, copies these libraries inside the app bundle, and
+      fixes both them and the executable to be ready for distribution... all
+      this with a single command on the teminal! It will also work if your
+      program uses plug-ins that have dependencies too.
