+-- Example lsyncd configuration for syncing with an Amazon S3 bucket
+--
+-- This requires the official AWS CLI to be available, and that credentials
+-- bet set up through some external method, such as environment variables,
+-- IAM profiles or the AWS SDK configuration.
+--
+-- The AWS CLI sync exclude rules are not as powerful as the ones supported by
+-- lsyncd. Hence, some of the do not translate perfectly. For example, '*'
+-- (asterisk) matches slashes, while it does not in lsyncd. Hence it is a good
+-- idea to only use exclude patterns for full directories, either by using a
+-- trailing / (slash) or ** (double asterisk), as those will be correctly
+-- translated.
+--
+-- An initialSync options is provided as a convenience, since it's not easy to
+-- make sure exclusion rules match when doing it manually. It will *pull* from
+-- the target bucket to the local dir (the opposite of the regular behavior)
+-- then exit immediately.
