[\fIdefault_client_options\fP]
[\fB/v\fP:<server>[:port]]
[\fB/version\fP]
[\fB/help\fP]
.SH DESCRIPTION
.B @MANPAGE_NAME@
is a wayland Remote Desktop Protocol (RDP) client which is part of the FreeRDP project. A RDP server is built-in to many editions of Windows.. Alternative servers included ogon, gnome-remote-desktop, xrdp and VRDP (VirtualBox).
.SH OPTIONS
The wayland client also supports a lot of the \fIdefault client options\fP which are not described here. For details on those see the xfreerdp(1) man page.
.IP \fB/v:\fP\fI<server>[:port]\fP
The server hostname or IP, and optionally the port, to connect to.
.IP /version
Print the version and exit.
.IP /help
Print the help and exit.
.SH EXIT STATUS
.TP
.B 0
Successful program execution.
.TP
.B not 0
On failure.
