Hello,
        I would need an equivalent of Printf.sprintf where the 
format string is not constant, it is read from the command line.
The motivation is to let the user specify a template for file names,
such as "img%03d.png". Can this be achieved in Ocaml? It seems not, as 
Pervasives.string_of_format only accepts constant strings.
Or is there some external library useful for this task? 

For the moment I have started to implement it myself for the limited
set of format specifications I will need but if there is some more
elegant solution I would be interested to hear about it.

Thanks,

Jan
