field of user records. A string in DNS domain name syntax.
`description` → A descriptive string for the group. This is similar to the
`realName` field of user records, and accepts arbitrary strings, as long as
they follow the same GECOS syntax requirements as `realName`.

`realName` → The real name of the user, a string. This should contain the user's
real ("human") name, and corresponds loosely to the GECOS field of classic UNIX
user records. When converting a `struct passwd` to a JSON user record this
field is initialized from GECOS (i.e. the `pw_gecos` field), and vice versa
when converting back. That said, unlike GECOS this field is supposed to contain
only the real name and no other information.
