Basically, usage is liek a more flexible version of printf.  You can 
supply optional format strings plus the stuff you want to print.  It's 
really meant to be used via writef of string.format though.  Do you have 
any specific questions?

well, Murphy's Law hit me again on this subject..
i was looking for a way to convert my md5 digest into a hexdecimal string, 
and only after i posted the question
i saw std.string.format..
but still, my main question is what exactly is the parameter list for 
doFormat ?
how does it look like ?

Cheers,

This is what std.md5.printDigest() looks like:

/* Prints a message digest in hexadecimal.
 */
void printDigest(ubyte digest[16])
{
    foreach (ubyte u; digest)
        printf("%02x", u);
}

I think what you're looking for is std.string.format(), not
std.format.doFormat().
