.\"
.SH SYNOPSIS
\fBscalarun\fR [ <\fIoptions\fR> ] <\fIsource files\fR> [ -- <\fImodule\fR> [ <\fIargs\fR> ] ]
.\"
.\" ############################### PARAMETERS ###############################
.\"
.SH PARAMETERS
.TP
<\fIoptions\fR>
Command line options. See \fBOPTIONS\fR below.
.TP
<\fIsource files\fR>
One or more source files to be interpreted (such as MyClass.scala).

.TP
<\fIargs\fR>

.\"
.\" ############################## DESCRIPTION ###############################
.\"
.SH DESCRIPTION
The \fBscalarun\fR utility interpretes a Scala application. It does this by
loading the class <\fImodule\fR> 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.
.PP
The Scala interpreter 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.
