There are two ways to specify the destination directory for dvdauthor to
write the complete DVD contents: via the “-o” command line option, or
the “dest” attribute on the “dvdauthor” tag in the XML file. If both are
specified, the latter overrides the former.
However, this seems to me to be backwards. It is usual in Unix tools for
the option that it is easiest for the user to change to take the highest
precedence. Thus, in general, you have an ordering from highest to
lowest precedence as follows (delete where inapplicable for any
particular setting):
command-line option
environment variable setting
user pref in ~/.whatever
systemwide config in /etc
perhaps default setting in /usr/share
hard-coded
In this case we also have a setting inside an input file specified on
the command line. I'm not sure whether that should come between the
first and second items in the above list, or the second and third; I'm
thinking perhaps the latter, since the contents of a file are harder to
change than resetting an environment variable.
(OK, so the point is moot in this case, since there is no environment
variable setting for dvdauthor's destination directory...)
Thoughts, anyone?
