    Sample ouput of this analysis script (will be added in commit log):

    Pretty printing 9p simpletrace log ...
    TGETATTR (tag = 1 , fid = 0 , request_mask = 0x7ff )
    RGETATTR (tag = 1 , result_mask = 0x7ff , mode = 040777 , uid = 500 
, gid = 500 )
    TXATTRWALK (tag = 1 , fid = 0 , newfid = 1 , xattr name = 36832096 )
    RXATTRWALK (tag = 1 , xattrsize  = 18446744073709551555 )
    TXATTRWALK (tag = 1 , fid = 0 , newfid = 1 , xattr name = 36744768 )
    RXATTRWALK (tag = 1 , xattrsize  = 18446744073709551555 )
    TGETATTR (tag = 1 , fid = 1 , request_mask = 0x3fff )
    RGETATTR (tag = 1 , result_mask = 0x17ff , mode = 040777 , uid = 
500 , gid = 500 )
    TWALK (tag = 1 , fid = 1 , newfid = 2 , nwnames = 1 )
    RWALK (tag = 1 , nwnames = 1 , qids = 0x230aea0 )
