Installing and uninstalling Porcupine applications is quite straightforward. After downloading the application's PPF file copy it inside the Porcupine installation folder. Before installing, stop Porcupine server. Then use the pakager utility:
python pakager.py -i -p [path to application's ppf file]
or
python pakager.py --install --package=[path to application's ppf file]
Likewise, before unistalling a Porcupine application make sure that Porcupine is not running. Then type the following:
python pakager.py -u -p [path to application's ppf file]
or
python pakager.py --uninstall --package=[path to application's ppf file]
