+
+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/foo) 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.
