+  crecall(<channel>[, <lines> [, <start line> [, <osep> [, <timestamps?> ]]]])
+
+  This function is the functional form of @chan/recall, and returns a
+  string containing the recalled lines from the channel, separated by
+  <osep>. If <timestamps?> is a true value, the recalled lines will
+  include their timestamps; otherwise, they will not.

   Channel functions work with the channel system.
