JDB as of JDK 1.2
.................

The following JDB options are useful when using DDD with JDB (from JDK
1.2) as inferior debugger.

`-attach ADDRESS'
     attach to a running virtual machine (VM) at ADDRESS using standard
     connector

`-listen ADDRESS'
     wait for a running VM to connect at ADDRESS using standard
     connector

`-listenany'
     wait for a running VM to connect at any available address using
     standard connector

`-launch'
     launch VM immediately instead of waiting for `run' command

   These JDB options are forwarded to the debuggee:

`-verbose[:class|gc|jni]'
`-v'
     Turn on verbose mode.

`-DNAME=VALUE'
     Set the system property NAME to VALUE.

`-classpath PATH'
     List directories in which to look for classes.  PATH is a list of
     directories separated by colons.

`-X OPTION'
     Non-standard target VM option

JDB as of JDK 1.1

The following JDB options are useful when using DDD with JDB (from JDK
1.1) as inferior debugger.

`-host HOSTNAME'
     host machine of interpreter to attach to

`-password PSSWD'

   These JDB options are forwarded to the debuggee:
