--
-- Gets information about all of the versions of a bot.
--
-- The @GetBotVersions@ operation returns a @BotMetadata@ object for each
-- version of a bot. For example, if a bot has three numbered versions, the
-- @GetBotVersions@ operation returns four @BotMetadata@ objects in the
-- response, one for each numbered version and one for the @$LATEST@
-- version.
--
-- The @GetBotVersions@ operation always returns at least one version, the
-- @$LATEST@ version.
--
-- This operation requires permissions for the @lex:GetBotVersions@ action.
--
-- This operation returns paginated results.
