+        Usage: play [OPTIONS] [--help]
+
+        The play command enables you to replay code from files and methods as if they
+        were entered directly in the Pry REPL.
+
+        play --lines 149..153   # assumes current context
+        play -i 20 --lines 1..3 # assumes lines of the input expression at 20
+        play -o 4               # the output of an expression at 4
+        play Pry#repl -l 1..-1  # play the contents of Pry#repl method
+        play -e 2               # play from specified line until end of valid expression
+        play hello.rb           # play a file
+        play Rakefile -l 5      # play line 5 of a file
+        play -d hi              # play documentation of hi method
+        play hi --open          # play hi method and leave it open
