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 writes and possibly updates and deletes are done and errors
       are only counted. The default log file name is myisam.log for
       myisamlog and isam.log for isamlog if no log_file argument is
       given. If tables are named on the command line, only those tables
       are updated.
