			The ThinLinc Client is a remote desktop client used to connect to a ThinLinc
			Server. With ThinLinc you are able to get access to Linux desktops and
			applications.
		
      
			You can use the ThinLinc Client to connect to an existing ThinLinc Server. You
			can also set up your own ThinLinc Server. The ThinLinc Server can be downloaded
			for free from https://www.cendio.com for Linux machines. The ThinLinc Server is
			free to use for a limited amount of concurrent users per organization.
		
      
			ThinLinc is a software that enables organizations to implement a
			Linux server-based computing (SBC) infrastructure. By centralizing
			computing resources in the data center rather than distributing them
			amongst end-users, IT systems become more efficient, secure, and
			accessible. End-users' desktops and applications are published from
			a central location, providing a seamless and familiar environment
			regardless of which device the user is connecting from, or the user
			location. Redundancy, inherent in a server-based solution, increases
			the availability as well.
		
      
			ThinLinc combines the tools and infrastructure required for
			Linux-based SBC into a mature, stable, and fully-supported package.
			It consists of both server-side components (session-broker,
			load-balancer, administration interface, etc.) and end-user
			components (client software, customization tools, etc.) to provide a
			complete solution.
		
      
			NOTE: This package is not verified by, affiliated with, or supported
			by Cendio AB.

Rymdport (formerly wormhole-gui) is a cross-platform application that lets you easily and safely share files, folders, and text between devices. The data is sent securely with end-to-end encryption using the same protocol as magic-wormhole. This means that Rymdport can talk not only to itself, but also to other wormhole clients.
      The transfers are implemented using wormhole-william, a native Go implementation of magic-wormhole. As a result, Rymdport compiles into a native binary with no runtime dependencies while also outperforming the reference implementation of magic-wormhole.
