+# Shell-scripting libraries

+The `syndicate-sh` package includes `/usr/lib/syndicate/syndicate.sh`, an implementation of the
+[Syndicate Protocol](../protocol.md) for Bash. Scripts may take advantage of the library to
+interact with peers via system dataspaces, either as [supervised
+services](../operation/builtin/daemon.md) or as external programs making use of the [gatekeeper
+service](../operation/builtin/gatekeeper.md).
+
+Examples of both kinds of script are included in the [`syndicate-sh` git

+The `preserves-tools` package includes useful command-line utilities for working with
+[Preserves](../guide/preserves.md) values and schemas.
+
+At present, it includes the [`preserves-tool` Swiss-army-knife
+utility][preserves-tool], which is useful for
+
+ - converting between text and binary Preserves syntaxes;
+ - pretty-printing (indenting) text Preserves syntax;
+ - manipulating Preserves annotations;
+ - breaking down and filtering Preserves documents using [preserves
+   path](https://preserves.gitlab.io/preserves/preserves-path.html) selectors;
+ - and so on.
+
+See also the [`preserves-tool` documentation][preserves-tool].
