[--no-area] [--geometry[:window]=widthxheight] [--no-toolbar]

DESCRIPTION
RoadMap is a program for UNIX that displays street maps. The maps are
provided for example by the US Census Bureau. When a GPS receiver is
available RoadMap can track the current location of the vehicule on the
screen, continuously adjusting the position of the map; it can also
identify the name of the current street as well as the name of the next
intersection.
RoadMap can be used without a GPS receiver, as a static map viewer or
address finder.
More information is available in the RoadMap online help.
OPTIONS
Most options may also be set as preferences. In fact, when an option
matches a preferences item, using the option does modify the prefer‐
ences item as well. As a consequence the effect of theses options will
be permanent until the same option is used again or the associated
preference item has been changed. Because the same preferences are
used by roadmap and roadgps, using any of those options with one pro‐
gram will impact the other.
An option with no associated preference item behaves in a more tradi‐
tional way, i.e. its effect is valid for that command only.
--location=longitude,latitude
Set the current location point (see menu entry View/Show Loca‐
tion..). Preference item: Locations.Location.
--metric
Use the metric system for all units. Preference item: Gen‐
eral.Unit = metric.
--imperial
Use the imperial system for all units. Preference item: Gen‐
eral.Unit = imperial.
--no-area
Do not show the polygons (parks, hospitals, airports, etc..).
This option was created for debug purposes and is probably now
useless.
--geometry[:window]=widthxheight
Set the geometry of a specific RoadMap window, identified by
it's title. If no window title is provided, this defines the
geometry of the main window. If the window's title includes any
space, dashes can be used in place of the spaces (the goal here
is to be shell friendly). Preference item: Geometry.window.
--no-toolbar
Do not show the toolbar. Preference item: General.Toolbar = no.
--no-icon
Do not show any icon (presumably to keep as much space as possi‐
ble for the map). Preference item: General.Icons = no
--square
Show the boundaries of the maps index grid (a variant of the R-
Tree index). This option is for debug purpose only.
--trip Open the given tripname on startup.
--gps=url
Use the specified GPS source. Two URL formats only are sup‐
ported: "gpsd://host/" (access the GPS through a gpsd server)
and "file://path" or "path" (path must be a full path). As an
exception, this option is not sticky: it does override the
related preferences item, but the preferences are not modified.
The main rational for this behavior is to make it painless to
replay GPS logs.
--cache=number
Set the number of entries in the roadmap's map cache. To
increase performances, roadmap keeps the last used map files
mapped in memory. This option defines how many map files can be
mapped at a given time. The greater this number is, the more
system ressources (virtual memory page descriptors) roadmap will
use. Preference item: Map.Cache
--debug[=source,...]
Print debug messages. If a list of source files is provided,
only messages generated from within these source files are
printed.
--verbose
Enable some log messages (a subset of the debug messages).
--help Show a description of the program options and quit.
