Concatenate file sort by date

[new_kubunto]

Hello, i have text file that filename contain the date of creation (i.e 2010.05.02.log).
I would like to create a script that:
-Ask for start date
-Ask for end date
- Concatenate all file on the requested period by date order.

Any idea how to do it ?

where "in" is the name of the file containing, in
sorted order, all the log files--something like this:

read date_1;
read date_2;
awk '/'$date_1'/,/'$date_2'/ { print $0 }' <in >>out
