+// Command apget retrieves the ActivityPub object accessible at url
+// and prints a JSON-encoded representation to the standard output.
+//
+// Its usage is:
+//
+// 	apget [-m] url
+//
+// The flags understood are:
+//
+//	-m
+//		Print the activity as a RFC5322 message
+//
+// # Examples
+//
+// Deliver a Mastodon post to a local user using apsend:
+//
+// 	apget -m https://hachyderm.io/@otl/112093503066930591 | apsend otl
