mvn scala:script -DscriptFile=scripts/PrintHello.scala --> Does scripts folder to be part of the project?

Question

Maven Scala: I created a scala project using archetype:

mvn org.apache.maven.plugins:maven-archetype-plugin:1.0-alpha-7:create \
    -DarchetypeGroupId=org.scala-tools.archetypes \
    -DarchetypeArtifactId=scala-archetype-simple \
    -DarchetypeVersion=1.1 \
    -DremoteRepositories=http://scala-tools.org/repo-releases \
    -DgroupId=your.proj.gid -DartifactId=your-proj-id

Now, I want to run a script file using:

mvn scala:script as described here mvn scala:script \
    -DscriptFile=scripts/PrintHello.scala \
    http://scala-tools.org/mvnsites/maven-scala-plugin/usage_script.html

Any idea where to put my .Scala file? what does "scripts/" exactly refer to?

thx
