# drscheme(1)

The PLT Scheme programming environment

## NAME

drscheme - The PLT Scheme programming environment

## SYNOPSIS

**drscheme** \[ *Xoption ...* \] \[ *file ...* \]

## DESCRIPTION

DrScheme is the PLT Scheme programming environment.

The **drscheme** program treats non-switch command-line arguments as files to open.

## X OPTIONS

When running in X11, DrScheme accepts the following standard *Xoption*s: **-display** *disp*, **-geometry** *geom*, **-bg** *color*, **-background** *color*, **-fg** *color*, **-foreground** *color*, **-fn** *font*, **-font** *font*, **-iconic**, **-name** *name*, **-rv**, **-reverse**, **+rv**, **-selectionTimeout** *time*, **-synchronous**, **-title** *name*, **-xnllanguage** *lang*, **-xrm** *file*.

In addition, the option **-singleInstance** is treated like an X option (it must appear before all other options), and it runs MrEd in single-instance mode. In single-instance mode, when an existing instance is running with the same host and executable name, all non-option arguments are treated as file names and sent to the  existing instance.
