<!--
 | Here is another profile, activated by the system property 'target-env' with a value of 'dev',
 | which provides a specific path to the Tomcat instance. To use this, your plugin configuration
 | might hypothetically look like:
 |
 | ...
 | <plugin>
 |   <groupId>org.myco.myplugins</groupId>
 |   <artifactId>myplugin</artifactId>
 |
 |   <configuration>
 |     <tomcatLocation>${tomcatPath}</tomcatLocation>
 |   </configuration>
 | </plugin>
 | ...
 |
 | NOTE: If you just wanted to inject this configuration whenever someone set 'target-env' to
 |       anything, you could just leave off the <value/> inside the activation-property.
