### If it's a multi-instance app, meaning it can be installed several times independently
### The id of the app as stated in the manifest is available as $YNH_APP_ID
### The instance number is available as $YNH_APP_INSTANCE_NUMBER (equals "1", "2", ...)
### The app instance name is available as $YNH_APP_INSTANCE_NAME
###    - the first time the app is installed, YNH_APP_INSTANCE_NAME = ynhexample
###    - the second time the app is installed, YNH_APP_INSTANCE_NAME = ynhexample__2
###    - ynhexample__{N} for the subsequent installations, with N=3,4, ...
### The app instance name is probably what interests you most, since this is
### guaranteed to be unique. This is a good unique identifier to define installation path,
### db names, ...
