.SH SYNOPSIS
\fBscala\fR [ <\fIoptions\fR> ] <\fIclass file\fR> [ <\fIargs\fR> ]
.\"
.\" ############################### PARAMETERS ###############################
.\"
.SH PARAMETERS
.TP
<\fIoptions\fR>
Command line options. See \fBOPTIONS\fR below.
.TP
<\fIclass file\fR>
Name of the class to be invoked.
.TP
<\fIargs\fR>
Program arguments passed to the main function.
.\"
.\" ############################## DESCRIPTION ###############################
.\"
.SH DESCRIPTION
The \fBscala\fR utility launches a Scala application. It does this by starting
a Java runtime environment, loading a specified class, and invoking that
class’s \fBmain\fR method. The method must have the following signature:
.PP
          \fBdef\fR main(args: Array[String]): Unit
.PP
The method must not return any value, and it must accept a String array as a
parameter. By default, the first non-option argument is the name of the class
to be invoked. A fully-qualified class name should be used.
.PP
The Scala runtime searches for the startup class, and other classes used, in
three sets of locations: the bootstrap class path, the installed extensions,
and the user class path.
.\"
.\" ############################### OPTIONS ##################################
.\"
.SH OPTIONS
The launcher has a set of standard options that are supported on the current
runtime environment and will be supported in future releases. An additional
set of non-standard options are specific to the current virtual machine
implementation and are subject to change in the future. Non-standard options
begin with \fB-X\fR.
.TP
\fB\-classpath\fR <\fIpath\fR>
Specify where to find user class files (on Unix-based systems a
colon-separated list of paths, on Windows-based systems, a semicolon-separate
list of paths).
