+define Package/delve/description
+  Delve is a debugger for the Go programming language. The goal of the
+  project is to provide a simple, full featured debugging tool for Go.
+  Delve should be easy to invoke and easy to use. Chances are if you're
+  using a debugger, things aren't going your way. With that in mind,
+  Delve should stay out of your way as much as possible.
