Name : guacamole-server
Product : Fedora 35
Version : 1.3.0
Release : 9.fc35
URL :   https://guacamole.apache.org/
Summary : Server-side native components that form the Guacamole proxy
Description :
Guacamole is an HTML5 remote desktop gateway.

Guacamole provides access to desktop environments using remote desktop protocols
like VNC and RDP. A centralized server acts as a tunnel and proxy, allowing
access to multiple desktops through a web browser.

No browser plugins are needed, and no client software needs to be installed. The
client requires nothing more than a web browser supporting HTML5 and AJAX.

The main web application is provided by the "guacamole-client" package.
