Lists features available when creating a domain
This command outputs information about Virtualmin features that are available
on this system. It is useful for scripts that are designed to run on many
systems and need to check if some feature is available before creating a
virtual server or enabling it for a domain.
By default it lists features available for new top-level servers. However,
you can limit it to those that are available for a sub-server with the
C<--parent> flag, followed by a top-level server name. Similarly, the
C<--alias> and C<--subdom> flags can be used to show features for an alias
or sub-domain respectively.
Output is in table format by default, but you can switch to a more detailed
and easily parsed list with the C<--multiline> flag. Or to just get a list
of feature codes, use the C<--name-only> parameter.
