-  <!-- profiles
-   | This is a list of profiles which can be activated in a variety of ways, and which can modify
-   | the build process. Profiles provided in the settings.xml are intended to provide local machine-
-   | specific paths and repository locations which allow the build to work in the local environment.
-   |
-   | For example, if you have an integration testing plugin - like cactus - that needs to know where
-   | your Tomcat instance is installed, you can provide a variable here such that the variable is
-   | dereferenced during the build process to configure the cactus plugin.
-   |
-   | As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles
-   | section of this document (settings.xml) - will be discussed later. Another way essentially
-   | relies on the detection of a system property, either matching a particular value for the property,
-   | or merely testing its existence. Profiles can also be activated by JDK version prefix, where a
-   | value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'.
-   | Finally, the list of active profiles can be specified directly from the command line.
-   |
-   | NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact
-   |       repositories, plugin repositories, and free-form properties to be used as configuration
-   |       variables for plugins in the POM.
-   |
-   |-->
-  <profiles>
-    <!-- profile
-     | Specifies a set of introductions to the build process, to be activated using one or more of the
-     | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/>
-     | or the command line, profiles have to have an ID that is unique.
-     |
-     | An encouraged best practice for profile identification is to use a consistent naming convention
-     | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.
-     | This will make it more intuitive to understand what the set of introduced profiles is attempting
-     | to accomplish, particularly when you only have a list of profile id's for debug.

-     | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.
