   TODO: print the catalog (some USE catalog.db ????).

   Standalone program to read a MySQL binary log (or relay log);
   can read files produced by 3.23, 4.x, 5.0 servers. 

   Can read binlogs from 3.23/4.x/5.0 and relay logs from 4.x/5.0.
   Should be able to read any file of these categories, even with
   --start-position.
   An important fact: the Format_desc event of the log is at most the 3rd event
   of the log; if it is the 3rd then there is this combination:
   Format_desc_of_slave, Rotate_of_master, Format_desc_of_master.

      Bug fix: #23735
      Author: Chuck Bell
      Description:
        Windows opens stdin in text mode by default. Certain characters
        such as CTRL-Z are interpeted as events and the read() method
        will stop. CTRL-Z is the EOF marker in Windows. to get past this
        you have to open stdin in binary mode. Setmode() is used to set
        stdin in binary mode. Errors on setting this mode result in
        halting the function and printing an error message to stderr.
