Version: 1.1.
Menu path: to do.

Mult
   do N random addition sequences, followed by rearrangements. 
   Options are: 
     wagner       no branch-swapping 
     spr          use SPR branch swapping 
     tbr          use TBR branch swapping 
     [no]keepall  keep the trees from all replications 
     replic N     do N replications  
     hold N       save up to N trees per replication (only if swapping) 
     [no]ratchet  do ratchet as well (settings with "ratchet" command) 
     [no]drift    do drift as well (settings with "drift" command) 
     [no]wclus N  after adding N taxa to the wagner tree, start using 
                  node clusters (of size defined with "bbreak:clus SIZE"). 
                  Useful only for very large data sets (several K-taxa). 
     outfreq N    frequency for which reports are produced during branch 
                  swapping (default is every N=10 clips, but for large data 
                  sets this implies reports take too long to be produced). 

   Usage: "mult:options;" changes settings only; "mult=options;" runs 
   as well.  Entering "mult:;" current settings are reported.

Example: calculate an initial tree using SPR with 20 replications. 5 trees per replication will be saved.
