+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+\&\f(CW\*(C`gij\*(C'\fR is a Java bytecode interpreter included with \f(CW\*(C`libgcj\*(C'\fR.
+\&\f(CW\*(C`gij\*(C'\fR is not available on every platform; porting it requires a
+small amount of assembly programming which has not been done for all the
+targets supported by \fBgcj\fR.
+.PP
+The primary argument to \f(CW\*(C`gij\*(C'\fR is the name of a class or, with
+\&\f(CW\*(C`\-jar\*(C'\fR, a jar file.  Options before this argument are interpreted
+by \f(CW\*(C`gij\*(C'\fR; remaining options are passed to the interpreted program.
+.PP
+If a class name is specified and this class does not have a \f(CW\*(C`main\*(C'\fR
+method with the appropriate signature (a \f(CW\*(C`static void\*(C'\fR method with
+a \f(CW\*(C`String[]\*(C'\fR as its sole argument), then \f(CW\*(C`gij\*(C'\fR will print an
+error and exit.
+.PP
+If a jar file is specified then \f(CW\*(C`gij\*(C'\fR will use information in it to
+determine which class' \f(CW\*(C`main\*(C'\fR method will be invoked.
+.PP
+\&\f(CW\*(C`gij\*(C'\fR will invoke the \f(CW\*(C`main\*(C'\fR method with all the remaining
+command-line options.
+.PP
+Note that \f(CW\*(C`gij\*(C'\fR is not limited to interpreting code.  Because
+\&\f(CW\*(C`libgcj\*(C'\fR includes a class loader which can dynamically load shared
+objects, it is possible to give \f(CW\*(C`gij\*(C'\fR the name of a class which has
+been compiled and put into a shared library on the class path.
+.SH "OPTIONS"
+.IX Header "OPTIONS"
+.IP "\fB\-cp\fR \fIpath\fR" 4
+.IX Item "-cp path"
+.PD 0
+.IP "\fB\-classpath\fR \fIpath\fR" 4
+.IX Item "-classpath path"
+.PD
+Set the initial class path.  The class path is used for finding
+class and resource files.  If specified, this option overrides the
+\&\f(CW\*(C`CLASSPATH\*(C'\fR environment variable.  Note that this option is
+ignored if \f(CW\*(C`\-jar\*(C'\fR is used.
+.IP "\fB\-D\fR\fIname\fR\fB[=\fR\fIvalue\fR\fB]\fR" 4
+.IX Item "-Dname[=value]"
+This defines a system property named \fIname\fR with value \fIvalue\fR.
+If \fIvalue\fR is not specified then it defaults to the empty string.
+These system properties are initialized at the program's startup and can
+be retrieved at runtime using the \f(CW\*(C`java.lang.System.getProperty\*(C'\fR
+method.
+.IP "\fB\-ms=\fR\fInumber\fR" 4
+.IX Item "-ms=number"
+Equivalent to \f(CW\*(C`\-Xms\*(C'\fR.
+.IP "\fB\-mx=\fR\fInumber\fR" 4
+.IX Item "-mx=number"
+Equivalent to \f(CW\*(C`\-Xmx\*(C'\fR.
+.IP "\fB\-noverify\fR" 4
+.IX Item "-noverify"
+Do not verify compliance of bytecode with the \s-1VM\s0 specification. In addition,
+this option disables type verification which is otherwise performed on BC-ABI
+compiled code.
+.IP "\fB\-X\fR" 4
+.IX Item "-X"
+.PD 0
+.IP "\fB\-X\fR\fIargument\fR" 4
+.IX Item "-Xargument"
+.PD
+Supplying \f(CW\*(C`\-X\*(C'\fR by itself will cause \f(CW\*(C`gij\*(C'\fR to list all the
+supported \f(CW\*(C`\-X\*(C'\fR options.  Currently these options are supported:
+.RS 4
+.IP "\fB\-Xms\fR\fIsize\fR" 4
+.IX Item "-Xmssize"
+Set the initial heap size.
+.IP "\fB\-Xmx\fR\fIsize\fR" 4
+.IX Item "-Xmxsize"
+Set the maximum heap size.
+.IP "\fB\-Xss\fR\fIsize\fR" 4
+.IX Item "-Xsssize"
+Set the thread stack size.
+.RE
+.RS 4
+.Sp
+Unrecognized \f(CW\*(C`\-X\*(C'\fR options are ignored, for compatibility with
+other runtimes.
+.RE
+.IP "\fB\-jar\fR" 4
+.IX Item "-jar"
+This indicates that the name passed to \f(CW\*(C`gij\*(C'\fR should be interpreted
+as the name of a jar file, not a class.
+.IP "\fB\-\-help\fR" 4
+.IX Item "--help"
+.PD 0
+.IP "\fB\-?\fR" 4
+.IX Item "-?"
+.PD
+Print help, then exit.
+.IP "\fB\-\-showversion\fR" 4
+.IX Item "--showversion"
+Print version number and continue.
+.IP "\fB\-\-fullversion\fR" 4
+.IX Item "--fullversion"
+Print detailed version information, then exit.
+.IP "\fB\-\-version\fR" 4
+.IX Item "--version"
+Print version number, then exit.
+.IP "\fB\-verbose\fR" 4
+.IX Item "-verbose"
+.PD 0
+.IP "\fB\-verbose:class\fR" 4
+.IX Item "-verbose:class"
+.PD
+Each time a class is initialized, print a short message on standard error.
+.PP
+\&\f(CW\*(C`gij\*(C'\fR also recognizes and ignores the following options, for
+compatibility with existing application launch scripts:
+\&\f(CW\*(C`\-client\*(C'\fR, \f(CW\*(C`\-server\*(C'\fR, \f(CW\*(C`\-hotspot\*(C'\fR, \f(CW\*(C`\-jrockit\*(C'\fR,
