Examples:

```
  capexpr {j o r}               True if any one of j, o, or r are available
  capexpr {oh}                  True if both o and h are available
  capexpr {@2 @3 4 5 6}         2 or 3 available for anonymous or one of
                                  4, 5 or 6 is available for the user
  capexpr L                     True if the user is logged in
  capexpr !L                    True if the user is not logged in
```

The `L` pseudo-capability is intended only to be used on its own or with
the `!` prefix for implementing login/logout menus via the `mainmenu`
site configuration option:

```
Login     /login        !L  {}
Logout    /logout        L  {}
```

i.e. if the user is logged in, show the "Logout" link, else show the
"Login" link.
