+// Package awssmfs provides an interface to AWS Secrets Manager which allows you
+// to interact with the Secrets Manager API as a standard filesystem.
+//
+// This filesystem's behaviour complies with fstest.TestFS.
+//
+// Usage
+//
+// To use this filesystem, call New with a base URL. All reads from the
+// filesystem are relative to this base URL. Only the scheme "aws+sm" is
+// supported. The URL may be an opaque URI (with no leading "/" in the path), in
+// which case secrets with names starting with "/" are ignored. If the URL path
+// does begin with "/", secrets with names not starting with "/" are instead
+// ignored.
+//
+// To scope the filesystem to a specific path, use that path on the URL. For
+// example, for a filesystem that can only read secrets with names starting with
+// "/prod/foo/", you would use a URL like:
+//
+//	aws+sm:///prod/foo/
+//
+// And for a filesystem that can only read secrets with names starting with
+// "prod/bar/", you would use the following opaque URI:
+//
+//	aws+sm:prod/bar/
+//
+// Configuration
+//
+// The AWS Secrets Manager client is configured using the default credential
+// chain (see https://aws.github.io/aws-sdk-go-v2/docs/configuring-sdk/#specifying-credentials
+// for more information).
+//
+// If you require more customized configuration, you can override the default
+// client with the WithSMClientFS function.
