This manual refers to the following directory: $SPLUNK_HOME/etc/apps/splunk_app_framework_documentation but it doesn't exist. Is the source available for download or do I have to type it all in?
The above document has been updated to provide the location of the Dev_tutorial app, which you can download and install in your $SPLUNK_HOME/etc/apps directory. This is the same source code included in the documentation: http://docs.splunk.com/Documentation/Splunk/6.0.3/Module/Gettingstartedexample
You can copy it from here: http://docs.splunk.com/Documentation/Splunk/6.0.3/Module/Gettingstartedexample.
The reference in question is: http://docs.splunk.com/Documentation/Splunk/6.0.3/Module/Anatomyofanapp
