=head1 SYNOPSIS
In many situations, users may want to specify patterns to match but don't need the full power of regexps. Wildcards make one of those sets of simplified rules. This module converts wildcard expressions to Perl regular expressions, so that you can use them for matching.
-It handles the C<*> and C<?> jokers, as well as Unix bracketed alternatives C<{,}>, but also C<%> and C<_> SQL wildcards. It can also keep original C<(...)> groups. Backspace (C<\>) is used as an escape character.
+It handles the C<*> and C<?> jokers, as well as Unix bracketed alternatives C<{,}>, but also C<%> and C<_> SQL wildcards. If required, it can also keep original C<(...)> groups or C<^> and C<$> anchors. Backspace (C<\>) is used as an escape character.
Typesets that mimic the behaviour of Windows and Unix shells are also provided.

-Notifies to convert the metacharacters that corresponds to the predefined type C<$type>. C<$type> can be any of C<'jokers'>, C<'sql'>, C<'commas'>, C<'brackets'>, C<'win32'> or C<'unix'>. An unknown or undefined value defaults to C<'unix'>, except for C<'dos'>, C<'os2'>, C<'MSWin32'> and C<'cygwin'> that default to C<'win32'>. This means that you can pass C<$^O> as the C<$type> and get the corresponding shell behaviour. Returns the object.

=head2 C<< capture [ $captures E<verbar> set => $c1, add => $c2, rem => $c3 ] >>
Specifies the list of atoms to capture.
This module does not implement the strange behaviours of Windows shell that result from the special handling of the three last characters (for the file extension). For example, Windows XP shell matches C<*a> like C<.*a>, C<*a?> like C<.*a.?>, C<*a??> like C<.*a.{0,2}> and so on.
