+** Maxima
+   Maxima is an absolutely amazing tool for mathematical symbolic
+   processing.  And to make matters better, it's lispy. It's giving

+   The =maxima= package provides good Emacs integration, with syntax
+   highlighting for the DSL and a nice inferior process mode for the

+   extension, so want to open those files in =maxima-mode=.
