mysqld vs. mysql-server

[Murray Eisenberg]

After I install the port mysql55-server, I have among other things binaries

  /opt/local/lib/mysql55/bin/mysqld
  /opt/local/share/mysql55/support-files/mysql.server

What's the difference? 

(I haven't been able to find anything on-line about binary mysql.server, and the two guides on setting up LAMP with MacPorts that I've been using -- 

  http://muddledramblings.com/rumblings-from-the-secret-labs/lamp-server-from-scratch-with-macports/
  https://trac.macports.org/wiki/howto/MAMP

seem to talk only about mysql.server, not mysqld.)
