.SH DESCRIPTION
\fBnaturalstrcmp\fP is an alphanumerical comparison function that ensures
\fBx12 > x2\fP for example.
First, the alphabetical part of the string is compared, using \fBstrcmp\fP(3),
then, if it has trailing numbers, they are compared using a numerical function.
.SH RETURN VALUES
\fBnaturalstrcmp\fP has the same return values than the standard library
\fBstrcmp\fP(3) function.
