 Remarks
             Launch permissions fall into three categories:
            
             1. public:
             The owner of the AMI granted launch permissions for the AMI to the
             all group. All users have launch permissions for these AMIs.
            
             2. explicit:
             The owner of the AMI granted launch permissions to a specific user.
            
             3. implicit:
             A user has implicit launch permissions for all AMIs he or she
             owns.
            
             The list of AMIs returned can be modified by specifying AMI IDs,
             AMI owners, or users with launch permissions. If no options are
             specified, Amazon EC2 returns all AMIs for
             which the user has launch permissions.
            
             If you specify one or more AMI IDs, only AMIs that have the
             specified IDs are returned. If you specify an invalid AMI
             ID, a fault is returned. If you specify an AMI ID for which
             you do not have access, it will not be included in the returned
             results.
            
             If you specify one or more AMI owners, only AMIs from the
             specified owners and for which you have access are returned. The
             results can include the account IDs of the
             specified owners, amazon for AMIs owned by Amazon or self for AMIs that you
             own.
            
             If you specify a list of executable users, only users that have
             launch permissions for the AMIs are returned. You can specify account IDs
             (if you own the AMI(s)), self for AMIs for which you own or have
             explicit permissions, or all for public AMIs.
