+@comment GNU
+@item GLOB_BRACE
+If this flag is given the handling of braces in the pattern is changed.
+It is now required that braces appear correctly grouped.  I.e., for each
+opening brace there must be a closing one.  Braces can be used
+recursively.  So it is possible to define one brace expression in
+another one.  It is important to note that the range of each brace
+expression is completely contained in the outer brace expression (if
+there is one).
+
+The string between the mathing braces is separated into single
+expressions by splitting at @code{,} (comma) characters.  The commas
+themself are discarded.  Please note what we said above about recursive
+brace expressions.  The commas used to separate the subexpressions must
+be at the same level.  Commas in brace subexpressions are not matched.
+They are used during expansion of the brace expression of the deeper
+level.  The example below shows this
+
+@smallexample
+glob ("@{foo/@{,bar,biz@},baz@}", GLOB_BRACE, NULL, &result)
+@end smallexample
+
+@noindent
+is equivalent to the sequence

+@item GLOB_NOMAGIC

+
+@comment glob.h
+@comment GNU
+@item GLOB_TILDE
+If this flag is used the character @code{~} (tilde) is handled special
+if it appears at the beginning of the pattern.  Instead of being taken
+verbatim it is used to represent the home directory of a known user.
+
+If @code{~} is the only character in pattern or it is followed by a
+@code{/} (slash), the home directory of the process owner is
+substituted.  Using @code{getlogin} and @code{getpwnam} the information
+is read from the system databases.  As an example take user @code{bart}
+with his home directory at @file{/home/bart}.  For him a call like
+
+@smallexample
+glob ("~/bin/*", GLOB_TILDE, NULL, &result)
+@end smallexample
+
+@noindent
+would return the contents of the directory @file{/home/bart/bin}.
+Instead of referring to the own home directory it is also possible to
+name the home directory of other users.  To do so one has to append the
+user name after the tilde character.  So the contents of user
+@code{homer}'s @file{bin} directory can be retrieved by
+
+@smallexample
+glob ("~homer/bin/*", GLOB_TILDE, NULL, &result)
+@end smallexample
+
+This functionality is equivalent to what is available in C-shells.
