~lidlut-tabwed-pillex-ridrup
```
## `%fake`
A `%fake` scry checks whether the current ship is fake (a development ship
booted with the `-F` option). The type returned is a `?`.
#### Example
On a fake `~zod`:
```
> .^(? %j /=fake=)
%.y
```
On a real planet:
```
> .^(? %j /=fake=)
%.n
```
## `%life`
A `%life` scry gets the current `life` (key revision number) of a ship if known, otherwise it crashes. It takes a ship as its `path` and the type returned is a `@ud`.
