+This package provides the `#lang repltest` meta-language, which can be used to turn the transcript of an interactive racket session into a series of tests.
+
+Usage:
+
+```
+raco pkg install repltest
+```
+
+Then write a file using the repltest meta-language, containing definitions at the top and interactions after the first prompt (by default the prompt is `"> "`, I will add customization options later).
+
+```
+#lang debug repltest typed/racket
+;; There is a problem if there is a comment before a prompt, as comments aren't
+;; gobbled-up by the preceeding read.
