I'd typically assume that every server has its own settings.conf.  If
that is not
the case, you can call set_setting_default *before* loading the settings
file, which
will change the default value for the calling process.  Of course, you
should not put
a value in the config file in that case.

This only lists settings in the calling module.  To enumerate all settings,
you need setting(Module:Name, Value).  That is similar to
current_predicate/1
and all other module-sensitive predicates.  P.s. mode(-,-) was broken.  Just
pushed a patch.

It seems to be defined in ClioPatria's parms.pl.  At some point, the overall
idea was to rebase a server by changing the HTTP path alias for root.  This
change never materialized.   So, the above only works for ClioPatria.
Otherwise
you must define http:prefix.  It is a bit of a mess :-(  Possibly the right
solution is to add it to library(http/http_path) and decide we won't change
this further?
