SD-packaged
applications can use interactive control scripts to query a user
and obtain installation or configuration information that cannot
be known at package time. For example, a different hardware or OS
may require the software to be installed to be configured differently.
Or, some software may need information such as IP address, hostname,
for its configuration.
SD runs the interactive control scripts by the swask
command or by the ask default option for the
swinstall and swconfig commands.
(SD does not query the user but the control script does.)
