<P>This group of actions is available whenever there exists a debug launcher that knows how to
run the current program. Various launchers may all make offers to run the current program, each
of which is presented as a item in this group. Not all offers are guaranteed to work. For
example, an offer to launch the program remotely via SSH depends on the host's availability and
the user's credentials. The offers are ordered by most recent activation. The most recent offer
used is the default one-click launcher for the current program. Each launcher may check various
conditions before making an offer. Most commonly, it will check that there is a suitable
debugger for the current program's architecture (language) on the local system, that the
program's original executable image still exists on disk, and that the user has permission to
execute it. A launcher may take any arbitrary action to run the program. Most commonly, it
starts a new connection suitable for the target, and then launches the program on that
connection. If <A href=
"help/topics/DebuggerObjectsPlugin/DebuggerObjectsPlugin.html#record_automatically">Record
Automatically</A> is enabled, this will provide a one-click action to debug the current
program. This is similar to the <A href=

action in the Commands and Objects window, except this one does not require an existing

<P>The launch offers are presented in two places. First, they are listed as drop-down items
from the "Debug Program" action in the main toolbar. When activated here, there are typically
no further prompts. One notable exception is SSH, where authentication may be required. Second,
they are listed under the <SPAN class="menu">Debugger &rarr; Debug Program</SPAN> menu. When
activated here, the launcher should prompt for arguments. The chosen arguments are saved as the
default for future launches of the current program.</P>

* @implNote The returned value cannot be a {@link TargetObjectRef} unless the value represents

* Furthermore, such links cannot be resolved -- though they can be substituted for

* ought to be a rare occurrence -- then fetching {@code A[1]} must return a ref to
* {@code B[1]}. It must not return {@code C[1]} nor a ref to it. The reason deals
* with caching and updates. If a request for {@code A[1]} were to return
* {@code C[1]}, a client may cache that result. Suppose that client then observes a
