.SH NAME
scalac \- Compiler for the Scala language
.\"
.\" ############################### SYNOPSIS #################################
.\"
.SH SYNOPSIS
\fBscalac\fR [ <\fIoptions\fR> ] <\fIsource files\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 compiled (such as MyClass.scala).
.\"
.\" ############################## DESCRIPTION ###############################
.\"
.SH DESCRIPTION
The \fBscalac\fR tool reads class and object definitions, written in the
Scala programming language, and compiles them into bytecode class files.
.PP
By default, the compiler puts each class file in the same directory as its
source file. You can specify a separate destination directory with -d (see
\fBOPTIONS\fR, below).
.\"
.\" ############################### OPTIONS ##################################
.\"
.SH OPTIONS
The compiler has a set of standard options that are supported on the current
development 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). This does not override the
built-in ("boot") search path.
.TP
\fB\-sourcepath\fR <\fIpath\fR>
Specify where to find input source files.
.TP
\fB\-bootclasspath\fR <\fIpath\fR>

Override location of installed extensions.
.TP
\fB\-d\fR <\fIdirectory\fR>
Specify where to place generated class files.
.TP
\fB\-encoding\fR <\fIencoding\fR>
Specify character encoding used by source files.

Read symbol files for separate compilation: (\fIyes\fR, \fIno\fR).
.TP
\fB\-target:\fR<\fItarget\fR>
Specify which backend to use (\fIjvm\fR, \fImsil\fR).
.TP
\fB\-r\fR <\fIassembly files\fR>
CLR Assemblies referenced by the source program (only relevant with
option '-target:msil').
.TP
\fB\-o\fR <\fIassembly name\fR>
Name of the output assembly (only relevant with option '-target:msil').
.TP
\fB\-version\fR
Print product version and exit.
