Why is there a /etc/init.d/mysql file on this Slackware machine? How could it have gotten there?

A client of my IT-consulting service owns a web-development shop. He's been having problems with a Slackware 12.0 server running MySQL 5.0.67. The machine was set up by the client's sysadmin, who left on bad terms. My client no longer employs a sysadmin.

As far as I can tell, the only copy of MySQL that's installed is the one described in /var/log/packages/mysql-5.0.67-i486-1:

PACKAGE NAME:     mysql-5.0.67-i486-1
COMPRESSED PACKAGE SIZE:     16828 K
UNCOMPRESSED PACKAGE SIZE:     33840 K
PACKAGE LOCATION: /var/slapt-get/archives/./slackware/ap/mysql-5.0.67-i486-1.tgz
PACKAGE DESCRIPTION:
mysql: mysql (SQL-based relational database server)

mysql: MySQL is a fast, multi-threaded, multi-user, and robust SQL
mysql: (Structured Query Language) database server.  It comes with a nice API
mysql: which makes it easy to integrate into other applications.

# To start MySQL automatically at boot, be sure this script is executable:
# chmod 755 /etc/rc.d/rc.mysqld

# Before you can run MySQL, you must have a database.  To install an initial
# database, do this as root:
#
#   su - mysql
#   mysql_install_db
#
# Note that step one is becoming the mysql user.  It's important to do this
# before making any changes to the database, or mysqld won't be able to write
# to it later (this can be fixed with 'chown -R mysql.mysql /var/lib/mysql').

# To allow outside connections to the database comment out the next line.
# If you don't need incoming network connections, then leave the line
# uncommented to improve system security.
#SKIP="--skip-networking"

# This file is public domain and comes with NO WARRANTY of any kind

# systems) and linked to /etc/rc3.d/S99mysql and /etc/rc0.d/K01mysql.
# When this is done the mysql server will be started when the machine is
# started and shut down when the systems goes down.

# Description: MySQL is a very fast and reliable SQL database engine.
### END INIT INFO

# If you install MySQL on some other places than /usr, then you
# have to do one of the following things for this script to work:
#
# - Run this script from within the MySQL installation directory
# - Create a /etc/my.cnf file with the following information:
#   [mysqld]
#   basedir=<path-to-mysql-installation-directory>
# - Add the above to any other configuration file (for example ~/.my.ini)
#   and copy my_print_defaults to /usr/bin
# - Add the path to the mysql-installation-directory to the basedir variable
#   below.
#
# If you want to affect other MySQL variables, you should make your changes
# in the /etc/my.cnf, ~/.my.cnf or other MySQL configuration files.

# If you change base dir, you must also change datadir. These may get
# overwritten by settings in the MySQL configuration files.

#basedir=
#datadir=

An unimportant aside: The previous users of the machine kept a messy home directory. Their home directory was /root. I've pasted a copy at http://www.pastebin.ca/2167496.

My question:

Why is there a /etc/init.d/mysql file on this Slackware machine? How could it have gotten there?

P.S. This question is far from perfect. Please feel free to edit it.
