Comment 3 for bug 1346481

From IRC:
14:47 < jdstrand> Chipaca: actually, I do have another question-- if app_id is
                  specified, should it be the click package name or the appname
                  (ie, the key to the hook database in the click manifest?)
14:47 < jdstrand> or something else?
14:47 < Chipaca> jdstrand: the "short id", ie unversioned app id, of one of the
                 apps in the package
14:47 < Chipaca> and
14:47 < Chipaca> ok, let me be clearer
14:48 < jdstrand> oh, so the APP_ID minus the version, ie <pkgname>_<appname>?
14:48 < Chipaca> jdstrand: if app_id is present, it must match
                 ${pkg}_${appname} of the app that has the desktop hook
14:48 < jdstrand> (assuming APP_ID is <pkgname>_<appname>_<version>)
14:48 < Chipaca> yes
14:48 < jdstrand> ok, thanks!
14:48 < jdstrand> I'll add checks for all that
