-=head1 NOTES

-=over 4

-
-Mac OS (Classic) users should note a few differences:
-
-=over 4
-
-=item *
-
-The path separator is ':', not '/', and the current directory is denoted
-as ':', not '.'. You should be careful about specifying relative pathnames.
-While a full path always begins with a volume name, a relative pathname
-should always begin with a ':'. If specifying a volume name only, a
-trailing ':' is required.
-
-=item *
-
-C<$File::Find::dir> is guaranteed to end with a ':'. If C<$_>
-contains the name of a directory, that name may or may not end with a
-':'. Likewise, C<$File::Find::name>, which contains the complete
-pathname to that directory, and C<$File::Find::fullname>, which holds
-the absolute pathname of that directory with all symbolic links resolved,
-may or may not end with a ':'.
-
-=item *
-
-The default C<untaint_pattern> (see above) on Mac OS is set to
-C<qr|^(.+)$|>. Note that the parentheses are vital.
-
-=item *
-
-The invisible system file "Icon\015" is ignored. While this file may
-appear in every directory, there are some more invisible system files
-on every volume, which are all located at the volume root level (i.e.
-"MacintoshHD:"). These system files are B<not> excluded automatically.
-Your filter may use the following code to recognize invisible files or
-directories (requires Mac::Files):
-
- use Mac::Files;
-
- # invisible() -- returns 1 if file/directory is invisible,
- # 0 if it's visible or undef if an error occurred
-
- sub invisible($) {
- my $file = shift;
- my ($fileCat, $fileInfo);
- my $invisible_flag = 1 << 14;
-
- if ( $fileCat = FSpGetCatInfo($file) ) {
- if ($fileInfo = $fileCat->ioFlFndrInfo() ) {
- return (($fileInfo->fdFlags & $invisible_flag) && 1);
- }
- }
- return undef;
- }
-
-Generally, invisible files are system files, unless an odd application
-decides to use invisible files for its own purposes. To distinguish
-such files from system files, you have to look at the B<type> and B<creator>
-file attributes. The MacPerl built-in functions C<GetFileInfo(FILE)> and
-C<SetFileInfo(CREATOR, TYPE, FILES)> offer access to these attributes
-(see MacPerl.pm for details).
-
-Files that appear on the desktop actually reside in an (hidden) directory
-named "Desktop Folder" on the particular disk volume. Note that, although
-all desktop files appear to be on the same "virtual" desktop, each disk
-volume actually maintains its own "Desktop Folder" directory.
