Usage: $0 [ECLIPSE_OPTIONS] [-b BUILD_LOG] [TARGET_OPTION]

Debug an executable, core-file, or an existing process using the Eclipse
C/C++ Stand-alone Debugger.  Eclipse command-line options may be passed
except for -vmargs which is being used to start up the Eclipse Debugger.

Operation modes:
  -h, --help                print this help, then exit

Indexing assist options:
  -b BUILD_LOG              build log to use for compiler includes/flags

Target options:
  -a [pid]                  attach using the optional pid or prompt for a pid 
  -c COREFILE               debug core-file (should also specify executable)
  -e EXECUTABLE [ARGS...]   debug given executable (passing ARGS to main)
  -r ADDRESS:PORT           debug toward the specified remote server. Can be
                            combined with the -a option.

The -e option must be used last as subsequent options are passed to main.

Specifying insufficient arguments for a particular target will result in a
dialog displayed to enter the required values for that target.  Specifying
no target option brings up a dialog for debugging an executable with the
executable path, program arguments, and build log filled in from the last -e
invocation, if one exists.
