Configuration files may be in a wide variety of formats.
The basic format is an option name followed by a value (argument) on the
same line. Values may be separated from the option name with a colon,
equal sign or simply white space. Values may be continued across multiple
lines by escaping the newline with a backslash.
Multiple programs may also share the same initialization file.
Common options are collected at the top, followed by program specific
segments. The segments are separated by lines like:
@example
[[=(. UP-PROG-NAME)=]]
@end example
@noindent
or by
@example
<?program [= prog-name =]>
@end example
@noindent
Do not mix these within one configuration file.
Compound values and carefully constructed string values may also be
specified using XML syntax:
@example
<option-name>
<sub-opt>...<...>...</sub-opt>
</option-name>
@end example
@noindent
yielding an @code{option-name.sub-opt} string value of
@example
"...<...>..."
@end example
@code{AutoOpts} does not track suboptions. You simply note that it is a
hierarchicly valued option. @code{AutoOpts} does provide a means for searching
the associated name/value pair list (see: optionFindValue).[=
