If your build script needs to get information out of Lisp, then wrapping
-~format~, or even ~prin1~, around forms is annoying; so ~runlisp~ has a
+~format~, or even ~princ~, around forms is annoying; so ~runlisp~ has a
~-p~ option which prints the values of the forms it evaluates.
: $ runlisp -e '(+ 1 2)'

-If a form produces multiple values, then ~-p~ will print all of them
-separated by spaces, on a single line:
+If a form produces multiple values, then ~-p~ will print all of them, as

: $ runlisp -p '(floor 5 2)'
: 2 1
+There's also a ~-d~ option, which does the same thing as ~-p~, only it
+prints values as if by ~prin1~. For example,

+: $ runlisp -p '"Hello, world!"'
+: Hello, world!
+: runlisp -d '"Hello, world!"'

In addition to evaluating forms with ~-e~, and printing their values
-with ~-p~, you can also load a file of Lisp code using ~-l~.
+with ~-d~ and ~-p~, you can also load a file of Lisp code using ~-l~.
When ~runlisp~ is acting on ~-e~, ~-p~, and/or ~-l~ options, it's said
to be running in /eval/ mode, rather than its usual /script/ mode. In
