SYNOPSIS         top

       myisamlog [options] [log_file [tbl_name] ...]

DESCRIPTION         top

       myisamlog processes the contents of a MyISAM log file.

       Invoke myisamlog like this:

           shell> myisamlog [options] [log_file [tbl_name] ...]
           shell> isamlog [options] [log_file [tbl_name] ...]

       The default operation is update (-u). If a recovery is done (-r), all

       isam.log for isamlog if no log_file argument is given. If tables are
       named on the command line, only those tables are updated.
