+# Plumb
+
+## Overview
+
+plumb is a drop-in replacement for plan9's plumb command, that understands mime-types of local files and URLs.
+
+## Rules
+
+plumb will write plumb messages as the usual `type is text` for non-files, and non-URLs. When the content is one of those, however, it will set the type to that mime.
+
+```
+
+type is image/png
+type is text/html
+type is text/plain
+type is application/pdf
+
+```
+
+If the remote mimetype is `application/octet-stream`, which is a fallback when it cannot infer the mimetype this client will attempt to find a content-type field in any remote URL, finally setting the type to `text`.
