Force bsd_glob() to return an error when it encounters a directory it
cannot open or read. Ordinarily bsd_glob() continues to find matches.
+=item C<GLOB_LIMIT>
+
+Make bsd_glob() return an error (GLOB_NOSPACE) when the pattern expands
+to a size bigger than the system constant C<ARG_MAX> (usually found in
+limits.h). If your system does not define this constant, bsd_glob() uses
+C<sysconf(_SC_ARG_MAX)> or C<_POSIX_ARG_MAX> where available (in that
+order). You can inspect these values using the standard C<POSIX>
+extension.
+
=item C<GLOB_MARK>
Each pathname that is a directory that matches the pattern has a slash
backslashes, consider using Sarathy's File::DosGlob, which comes with
the standard Perl distribution.
+=item *
+
+Mac OS (Classic) users should note a few differences. Since
+Mac OS is not Unix, when the glob code encounters a tilde glob (e.g.
+~user) and the C<GLOB_TILDE> flag is used, it simply returns that
+pattern without doing any expansion.
+
+Glob on Mac OS is case-insensitive by default (if you don't use any
+flags). If you specify any flags at all and still want glob
+to be case-insensitive, you must include C<GLOB_NOCASE> in the flags.
+
+The path separator is ':' (aka colon), not '/' (aka slash). Mac OS users
+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.
+
+The specification of pathnames in glob patterns adheres to the usual Mac
+OS conventions: The path separator is a colon ':', not a slash '/'. A
+full path always begins with a volume name. A relative pathname on Mac
+OS must always begin with a ':', except when specifying a file or
+directory name in the current working directory, where the leading colon
+is optional. If specifying a volume name only, a trailing ':' is
+required. Due to these rules, a glob like E<lt>*:E<gt> will find all
+mounted volumes, while a glob like E<lt>*E<gt> or E<lt>:*E<gt> will find
+all files and directories in the current directory.
+
+Note that updirs in the glob pattern are resolved before the matching begins,
+i.e. a pattern like "*HD:t?p::a*" will be matched as "*HD:a*". Note also,
+that a single trailing ':' in the pattern is ignored (unless it's a volume
+name pattern like "*HD:"), i.e. a glob like E<lt>:*:E<gt> will find both
+directories I<and> files (and not, as one might expect, only directories).
+You can, however, use the C<GLOB_MARK> flag to distinguish (without a file
+test) directory names from file names.
+
+If the C<GLOB_MARK> flag is set, all directory paths will have a ':' appended.
+Since a directory like 'lib:' is I<not> a valid I<relative> path on Mac OS,
+both a leading and a trailing colon will be added, when the directory name in
+question doesn't contain any colons (e.g. 'lib' becomes ':lib:').
