# Getopt::Long Configuration.
sub Configure (@) {
my (@options) = @_;
Of course, it is important to choose the right separator string for
each purpose.
+Warning: What follows is an experimental feature.
+
+Options can take multiple values at once, for example
+
+ --coordinates 52.2 16.4 --rgbcolor 255 255 149
+
+This can be accomplished by adding a repeat specifier to the option
+specification. Repeat specifiers are very similar to the C<{...}>
+repeat specifiers that can be used with regular expression patterns.
+For example, the above command line would be handled as follows:
+
+ GetOptions('coordinates=f{2}' => \@coor, 'rgbcolor=i{3}' => \@color);
+
+The destination for the option must be an array or array reference.
+
+It is also possible to specify the minimal and maximal number of
+arguments an option takes. C<foo=s{2,4}> indicates an option that
+takes at least two and at most 4 arguments. C<foo=s{,}> indicates one
+or more values; C<foo:s{,}> indicates zero or more option values.
+
=head2 Options with hash values
If the option destination is a reference to a hash, the option will
The C<+> specifier is ignored if the option destination is not a scalar.
-=item = I<type> [ I<desttype> ]
+=item = I<type> [ I<desttype> ] [ I<repeat> ]
The option requires an argument of the given type. Supported types
are:
the option value is not otherwise specified. It should be omitted when
not needed.
+The I<repeat> specifies the number of values this option takes per
+occurrence on the command line. It has the format C<{> [ I<min> ] [ C<,> [ I<max> ] ] C<}>.
+
+I<min> denotes the minimal number of arguments. It defaults to 1 for
+options with C<=> and to 0 for options with C<:>, see below. Note that
+I<min> overrules the C<=> / C<:> semantics.
+
+I<max> denotes the maximum number of arguments. It must be at least
+I<min>. If I<max> is omitted, I<but the comma is not>, there is no
+upper bound to the number of argument values taken.
+
=item : I<type> [ I<desttype> ]
Like C<=>, but designates the argument as optional.
