Copy the files to the Mac Libs folder.
Go to the libraries folder and create an xml file with the same name as the 'a' file (without the lib prefix).
The content of this file should be:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<root>
<doclet-version-NOT-library-version>1.00</doclet-version-NOT-library-version>
<version>1</version>
<!-- this is optional. It allows you to add more references<dependsOn>AppTracker</dependsOn> -->
</root>
