+=============
+
+Description
+-----------
+This patch adds the ability to spawn a new terminal with ssh awareness, meaning
+that if your current selected client has an open ssh sesion, a newly created
+client will copy the ssh command and execute it. The spawning also carries over
+additional flags you have given to ssh. If your current client does not have an
+ssh session it executes the provided command.
+
+It works by crawling all of the processes for ssh sessions and traversing the
+process tree upwards to check if your current client is a parent of an ssh
+session.
+
+This patch borrows the `winpid` function from the swallow patch. My thanks to:

+Notes
+-----
+Since the patch relies on walking the process tree, which is OS-specific,
+compatibility with other operating systems is not guaranteed. If you want to
+help expand the list of supported plattforms please contact me.
