+      `stdoutisatty command` makes `command` think their stdout is a terminal,
+      even if it is actually being piped into another program (e.g. `less`).
+      This is most useful for preserving user-friendly, colored outputs.
+
+      For example, `stdoutisatty ls --color=auto | less` will always show
+      colored output, despite being piped into a pager.
