I use puppet to install a current JDK and tomcat.

package {
    [ "openjdk-6-jdk", "openjdk-6-doc", "openjdk-6-jre",
      "tomcat6", "tomcat6-admin", "tomcat6-common", "tomcat6-docs", 
      "tomcat6-user" ]:
    ensure => present,
}

Now I'd like to add

JAVA_HOME="/usr/lib/java"
export JAVA_HOME

to /etc/profile, just to get this out of the way. I haven't found a straightforward answer in the docs, yet. Is there a recommended way to do this?

In general, how do I tell puppet to place this file there or modify that file? I'm using puppet for a single node (in standalone mode) just to try it out and to keep a log of the server setup.
