## Launching GPSMan

If GPSMan was installed from a Debian or RPM package, just call `gpsman` from a shell or from the applications menu of the window manager (if it was set up by the package installation program).

When using a command line, like the Unix/Linux shell, call `gpsman.tcl` or use the shell script`gpsman.sh` (it must be configured first).

In this situation there could be a single argument with the path to the serial or USB port device, or the call has the form
`gpsman [OPTIONS] start travel [INTERVAL]`
that will be parsed as if in command-line mode, but then launches the graphical interface (this will only work with Garmin receivers).

In the case of a single argument, a USB port device can be given with the prefix `usb=`, as in `usb=/dev/ttyUSB0`, to enforce the use of the Garmin USB protocol when this is not the default protocol.

In other systems, execute `gpsman.tcl` with the Tcl/Tk `wish` program.
