rseed
   N    set random seed as N ( 0 = time ; default = 1 )  
   +N   increase random seed by N 
   *;   set a new random seed, at random 
   [;   in wagner trees, randomize insertion sequence 
   ];   in wagner trees, try insertions for new taxa from 
        top to bottom or from bottom up (=default) 
   :N;  in multiple randomizations, instead of making sure 
        that each new seed is different from the ones used 
        before, increase the seed by N.  This may save time 
        in very extensive randomizations (where checking 
        previous seeds takes time).  When N=0, checks previous 
        seeds (this the default). 
   !    use quick approximation for randomization (faster) 
   -    use careful randomizations (slower, more random; default)

Example: set random seed using time.
