+Cask, Eldev itself is fully written in Elisp and its configuration files are
+also Elisp programs.  For those familiar with the Java world, Cask can be seen
+as a parallel to Maven — it uses project description, while Eldev is sort of a
+parallel to Gradle — its configuration is a program on its own.")
