+// Token is a translation of the gotosocial token with the ExpiresIn fields replaced with ExpiresAt.
+//
+// Explanation for this: gotosocial assumes an in-memory or file database of some kind, where a time-to-live parameter (TTL) can be defined,
+// and tokens with expired TTLs are automatically removed. Since some databases don't have that feature, it's easier to set an expiry time and
+// then periodically sweep out tokens when that time has passed.
+//
+// Note that this struct does *not* satisfy the token interface shown here: https://github.com/superseriousbusiness/oauth2/blob/master/model.go#L22
+// and implemented here: https://github.com/superseriousbusiness/oauth2/blob/master/models/token.go.
+// As such, manual translation is always required between Token and the gotosocial *model.Token. The helper functions oauthTokenToPGToken
+// and pgTokenToOauthToken can be used for that.
