.PP
The provided options are passed to kaffe virtual machine\&. Available options are described in the section OPTIONS\&. The provided arguments are passed to the main function of the called class\&.

.SH "DESCRIPTION"

.PP
\fBkaffe\fR executes Java(tm) bytecode, either as a pure bytecode interpreter, or by doing "just\-in\-time" code conversion from the abstract code to the host machine's native code\&.

.PP
The specified \fIclassname\fR has to be a fully\-qualified classname (e\&.g\&. foo\&.bar\&.ClassName)\&. If \fBkaffe\fR is used with the \fB\-jar\fR flag, the class to execute is determined through the manifest file included in the specified Jar\-File \fIfilename\fR\&.

.PP
