    Each command parameter is prefixed with <b>--</b>.

    be appended to the existing option.
    If the environment variable with the same name as command line parameter but
    prefixed with <code>PR_</code> exists it will take precedence.
    For example:
<source>set PR_CLASSPATH=xx.jar</source>
</p>    
<p>is equivalent to providing
<source>--Classpath=xx.jar</source>

<section name="Installing services">
<p>
The safest way to manually install the service is to use the provided
<b>service.bat</b> script. Administrator privileges are required to run this
script.
</p>
<p>
<strong>NOTE:</strong> On Windows Vista or any later operating system with User
Account Control (UAC) enabled you will be asked for additional privileges
when 'Tomcat<version-major/>.exe' is launched by the script.<br/>
If you want to pass additional options to service installer as
<code>PR_*</code> environment variables, you have to either configure them
globally in OS, or launch the program that sets them with elevated privileges
(e.g. right-click on cmd.exe and select "Run as administrator"; on Windows 8
(or later) or Windows Server 2012 (or later), you can open an elevated command
prompt for the current directory from the Explorer
by clicking on the "File" menu bar). See issue <bug>56143</bug> for details.

<p>
<source>
Install the service named 'Tomcat6'
C:\> service.bat install
</source>
</p>
<p>
If using tomcat6.exe, you need to use the <b>//IS//</b> parameter.
</p>
<p>
<source>
Install the service named 'Tomcat6'
C:\> tomcat6 //IS//Tomcat6 --DisplayName="Apache Tomcat 6" \
C:\> --Install="C:\Program Files\Tomcat\bin\tomcat6.exe" --Jvm=auto \
C:\> --StartMode=jvm --StopMode=jvm \
C:\> --StartClass=org.apache.catalina.startup.Bootstrap --StartParams=start \
C:\> --StopClass=org.apache.catalina.startup.Bootstrap --StopParams=stop
</source>
</p>
</section>
<section name="Updating services">
<p>
To update the service parameters, you need to use the <b>//US//</b> parameter.
</p>
<p>
<source>
Update the service named 'Tomcat6
C:\> tomcat6 //US//Tomcat6 --Description="Apache Tomcat Server - http://tomcat.apache.org/ " \
C:\> --Startup=auto --Classpath=%JAVA_HOME%\lib\tools.jar;%CATALINA_HOME%\bin\bootstrap.jar
</source>
</p>
</section>
<section name="Removing services">
<p>
To remove the service, you need to use the <b>//DS//</b> parameter.<br/>
If the service is running it will be stopped and then deleted.
</p>
<p>
<source>
Remove the service named 'Tomcat6'
C:\> tomcat6 //DS//Tomcat6
</source>
</p>
</section>
<section name="Debugging services">
<p>
To run the service in console mode, you need to use the <b>//TS//</b> parameter.
The service shutdown can be initiated by pressing <b>CTRL+C</b> or
<b>CTRL+BREAK</b>.
If you rename the tomcat6.exe to testservice.exe then you can just execute the
testservice.exe and this command mode will be executed by default.
</p>
<p>
<source>
Run the service named 'Tomcat6' in console mode
C:\> tomcat6 //TS//Tomcat6 [additional arguments]
Or simply execute:
C:\> tomcat6
