They look something like:

Stack print options:
  -n, -number-of-frames NUMBER    number of frames to print. Use -n 0 or -n 
                                    all to print all frames.
  -f, -full-path                  print the full path to object files
  -a, -all                        Print all information that can be retrieved 
                                    about the stack
                                    this is equivalent to -print 
                                    functions,params,scopes,fullpath
  -v, -virtual                    Includes virtual frames in the stack trace.
                                    Virtual frames are artificial frames 
                                    corresponding to calls to inlined functions
  -c, -common                     print commonly used debug information:this 
                                    is equivalent to -print 
                                    functions,params,fullpath
      -print [item],...           itmes to print. Possible items:
                                    functions : print function names using 
                                    debug information
                                    scopes : print variables declared in each 
                                    scope within the function.
                                    params : print function parameters
                                    fullpath : print full executbale path
