Usage: $0 [OPTIONS]
  --basedir=path       The path to the MySQL installation directory.
  --builddir=path      If using --srcdir with out-of-directory builds, you
                       will need to set this to the location of the build
                       directory where built files reside.
  --cross-bootstrap    For internal use.  Used when building the MySQL system
                       tables on a different host than the target.
  --datadir=path       The path to the MySQL data directory.
                       If missing, the directory will be created, but its
                       parent directory must already exist and be writable.
  --defaults-extra-file=name
                       Read this file after the global files are read.
  --defaults-file=name Only read default options from the given file name.
  --force              Causes mysql_install_db to run even if DNS does not
                       work.  In that case, grant table entries that normally
                       use hostnames will use IP addresses.
  --help               Display this help and exit.                     
  --ldata=path         The path to the MySQL data directory. Same as --datadir.
  --no-defaults        Don't read default options from any option file.
  --keep-my-cnf        This option is enabled by default in Percona Server and 
                       is kept only for compatibility: don't try to create
                       my.cnf based on template.
                       Useful for systems with working, updated my.cnf.
                       Deprecated, will be removed in future version.
EOF1
  if ( $^O !~ m/^(MSWin32|cygwin)$/ ) {
    print <<EOF2;
  --random-passwords   Create and set a random password for all root accounts
                       and set the "password expired" flag,
                       also remove the anonymous accounts.
