Dear Paul,

I have looked at your class text. The addition of an interval of valid  
values for 'integer options' seems reasonable and should be included.  
Still, I think it should be directly added to AP_INTEGER_OPTION, instead  
of having a specific sub-class. It is just too small to justify a complete  
new class. The default range is min-integer to max-integer, and the help  
text will only display default ranges if the limits have been changed.

BTW: AP_INTEGER_INTERVAL_OPTION would be an option that takes an interval  
as the parameter. (--foo=1..10 or -b 20-40). But that is probably too  
specific for the library and not what you intended.

Adding an AP_DATE_OPTION class seems very interesting, though it would add  
a dependency of the argument library to the 'time' library (which - AFAIK  
- is currently not there).

Parsing dates from strings is also a complex job. Some of this work has  
been done in the XML libraries, but again we get into trouble of creating  
dependencies between libraries (there was a discussion between Colin and  
Eric sometime ago about this issues, but I do not know how this was  
resolved).
