@deftypefun int strverscmp (const char *@var{s1}, const char *@var{s2})
The @code{strverscmp} function compares the string @var{s1} against
@var{s2}, considering them as holding indices/version numbers. Return
value follows the same conventions as found in the @code{strverscmp}
function. In fact, if @var{s1} and @var{s2} contain no digits,
@code{strverscmp} behaves like @code{strcmp}.
Basically, we compare strings normaly (character by character), until
we find a digit in each string - then we enter a special comparison
mode, where each sequence of digit is taken as a whole. If we reach the
end of these two parts without noticing a difference, we return to the
standard comparison mode. There are two types of numeric parts:
"integral" and "fractionnal" (these laters begins with a '0'). The types
of the numeric parts affect the way we sort them:
@itemize @bullet
@item
integral/integral: we compare values as you would expect.
@item
fractionnal/integral: the fractionnal part is less than the integral one.
Again, no surprise.
@item
fractionnal/fractionnal: the things become a bit more complex.
if the common prefix contains only leading zeroes, the longest part is less
than the other one; else the comparison behaves normaly.

strverscmp ("foo.009", "foo.0")
@result{} <0 /* @r{idem, but with leading zeroes only.} */
@end smallexample
This function is especially usefull when dealing with filename sorting,
because filenames frequently hold indices/version numbers.
@code{strverscmp} is a GNU extension.
