+#!/usr/bin/env bash
+#
+# Intersystem communication via clipboard over SSH!
+# Transmits data using the clipboard via SSH session.
+#
+# Description:
+#
+# xclip-ssh does what the same says - xclip over SSH.
+# Works even with a remote host in a .onion service!
+# And even between virtual machines!
+#
+# Works around the following PoC:
+#
+# ssh -X <server>      # log in the remote system
+# DISPLAY=:0 xclip -o  # extracts remote's clipboard
+#
+# Usage:
+#
+# xclip-ssh send    <server> [stdin|data]
+# xclip-ssh receive <server> [stdout|xclip]
+#
+# Examples:
+#
+# cat /path/to/file | xclip-ssh send server
+# xclip-ssh send server "some text"
+# xclip-ssh receive server stdout > saved.txt
+
+# Parameters
