Display or apply log records from a Aria transaction log
found in the current directory (for now)

Note: Aria is compiled without -DIDENTICAL_PAGES_AFTER_RECOVERY
which means that the table files are not byte-to-byte identical to
files created during normal execution. This should be ok, except for
test scripts that tries to compare files before and after recovery.

Usage: aria_read_log OPTIONS [-d | -a] -h `aria_log_directory`
or
Usage: aria_read_log OPTIONS -h `aria_log_directory` --print-log-control-file

  -a, --apply         Apply log to tables: modifies tables! you should make a
                      backup first!  Displays a lot of information if not run
                      with --silent
  --character-sets-dir=name
                      Directory where character sets are.
  -c, --check         if --display-only, check if record is fully readable (for
                      debugging)
  -?, --help          Display this help and exit.
  -d, --display-only  display brief info read from records' header
  -e, --end-lsn=name  Alias for lsn-redo-end
  -e, --lsn-redo-end=name
                      Stop applying at this lsn during redo. If this option is
                      used UNDO:s will not be applied unless --lsn-undo-end is
                      given
  -E, --lsn-undo-end=name
                      Stop applying undo after this lsn has been applied
  -h, --aria-log-dir-path=name
                      Path to the directory where to store transactional log
  -P, --page-buffer-size=#
                      The size of the buffer used for index blocks for Aria
                      tables
  -l, --print-log-control-file
                      Print the content of the aria_log_control_file
  -o, --start-from-lsn=#
                      Start reading log from this lsn
  -C, --start-from-checkpoint
                      Start applying from last checkpoint
  -s, --silent        Print less information during apply/undo phase
  -T, --tables-to-redo=name
                      List of tables separated with , that we should apply REDO
                      on. Use this if you only want to recover some tables
  -t, --tmpdir=name   Path for temporary files. Multiple paths can be
                      specified, separated by colon (:)
  --translog-buffer-size=#
                      The size of the buffer used for transaction log for Aria
                      tables
  -u, --undo          Apply UNDO records to tables. (disable with
                      --disable-undo). Will be automatically set if
                      lsn-undo-end is used
                      (Defaults to on; use --skip-undo to disable.)
  -v, --verbose       Print more information during apply/undo phase
  -V, --version       Print version and exit.

Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf ~/.my.cnf
The following groups are read: aria_read_log
The following options may be given as the first argument:
--print-defaults          Print the program argument list and exit.
--no-defaults             Don't read default options from any option file.
The following specify which files/extra groups are read (specified before remaining options):
--defaults-file=#         Only read default options from the given file #.
--defaults-extra-file=#   Read this file after the global files are read.
--defaults-group-suffix=# Additionally read default groups with # appended as a suffix.

Variables (--variable-name=value)
