14					File::Spec::Cygwin - methods for Cygwin file specs
15
16					=head1 SYNOPSIS
17
18					require File::Spec::Cygwin; # Done internally by File::Spec if needed
19
20					=head1 DESCRIPTION
21
22					See L<File::Spec> and L<File::Spec::Unix>. This package overrides the
23					implementation of these methods, not the semantics.
24
25					This module is still in beta. Cygwin-knowledgeable folks are invited
26					to offer patches and suggestions.

34					=item canonpath
35
36					Any C<\> (backslashes) are converted to C</> (forward slashes),
37					and then File::Spec::Unix canonpath() is called on the result.
