+A theme for the 70s, makes fish even more powerful. It's equipped with a hell
+of a lot of nice functions and key bindings to speed up your workflow.
+
+The philosophy behind budspencer theme:
+
+* Delimit the prompt lines clearly to the output.
+* Produce output only if it contains relevant information.
+* Show useful notifications within the prompt.
+* Equip the prompt with toggle commands in order to change its style
+  interactively.
+* Store sessions in order to make frequently used commands quickly accessible.
+* Make navigation within the directory tree as easy as possible using
+  bookmarks and a directory history without duplicates.
+* Make histories quickly accessible with menus.
+* Don't stress your eyes. Use different colors in dark and bright environments.
