Now answering your question :) 

Name="src" means the folder related to the one where module.xml is situated on the development/testing or publishing machine.

In order to protect the IP you can use "Deployed packages" mode, see the documentation. Just include Deploy="true" in a resource element, and only compiled code will be installed. 

  <Resource Name="Sample.Demo.PKG" Deploy="true"/>

Load command locally still will import package with the source code, which is quite handy for development and testing.

Hi @Stephen Canzano !

Unit tests are not included into the package when you publish it into repository. So when you install the package on a target machine only "solution" classes will be installed, not unit-tests.

E.g. here is csvgen app. I you check the source code it contains "solution" classes in src folder here and unit-tests in /tests folder.

module XML for csvgen has resources, that will be packaged while published in the IPM registry:

<Resource Name="community.PKG"/>

and the unittests, that are being used only development phase and can be imported to the system via load command:

<UnitTest Name="/tests" Package="community.csvgen.UnitTests" Phase="test"/>

So when you install csvgen package, e.g.:

USER>zpm "install csvgen" 

you'll see only RESOURCES classes installed.

Thank you, @Steve Pisani !
