This program will convert any arbitrary XML file into equivalent
AutoGen definitions, and invoke AutoGen.

The template will be derived from either:
* the ``--override-tpl'' command line option
* a top level XML attribute named, "template"
The ``base-name'' for the output will similarly be either:
* the ``--base-name'' command line option
* the base name of the .xml file

The template will be derived from either:
.br
* the \fB--override-tpl\fP command line option
.br
* a top level XML attribute named, "template"
.br
One or the other \fBmust\fP be provided, or the program will
exit with a failure message.
.sp 1
The ``base-name'' for the output will similarly be either:
.br
* the \fB--base-name\fP command line option
.br
* the base name of the .xml file
END_DETAIL ;
prog-info-descrip = <<- END_DETAIL
The template used will be derived from either:
@itemize @bullet
@item
The @strong{--override-tpl} command line option
@item
A top level XML attribute named, "@code{template}"
@end itemize
@noindent
One or the other @strong{must} be provided, or the program will
exit with a failure message.
The @emph{base-name} for the output will similarly be either:
@itemize @bullet
@item
The @strong{--base-name} command line option.
@item
The base name of the @file{.xml} file.
@end itemize
The definitions derived from XML generally have an extra layer
of definition. Specifically, this XML input:
@example
<mumble attr="foo">
mumble-1
<grumble>
grumble, grumble, grumble.
</grumble>mumble, mumble
</mumble>
@end example
Will get converted into this:
@example
mumble = @{
grumble = @{
text = 'grumble, grumble, grumble';
@};
text = 'mumble-1';
text = 'mumble, mumble';
@};
@end example
Please notice that some information is lost. AutoGen cannot tell that
"grumble" used to lie between the mumble texts. Also please note that
you cannot assign:
@example
grumble = 'grumble, grumble, grumble.';
@end example
because if another "grumble" has an attribute or multiple texts,
it becomes impossible to have the definitions be the same type
(compound or text values).
