``property-list``
Return the list of top-level properties.
``profile-list``
Return the list of profiles and their contents. This is highly
implementation-specific, and may change any time. Currently, it returns
an array of options for each profile. Each option has a name and a value,
with the value currently always being a string. Note that the options array
is not a map, as order matters and duplicate entries are possible. Recursive
profiles are not expanded, and show up as special ``profile`` options.
