+unifdef copyright licence
+-------------------------
+
+All files in this package are distributed under the two-clause BSD
+copyright licence, except for the manual page unifdef.1 and the
+portability support code in the FreeBSD subdirectory, which all have
+a three-clause BSD copyright licence.
+
+Unifdef was derived from software contributed to Berkeley by Dave
+Yost. It was rewritten to support ANSI C by Tony Finch. The original
+version of unifdef.c carried the four-clause BSD copyright licence.
+None of its code remains in this version (though some of the names
+remain) so it now carries the more liberal two-clause licence.
+
+Unless otherwise stated, the files in this package are:
+
+  Copyright (c) 2002 - 2020 Tony Finch <[email protected]>
+
+unifdefall.sh is:
+
+  Copyright (c) 2002 - 2013 Tony Finch <[email protected]>
+  Copyright (c) 2009 - 2010 Jonathan Nieder <[email protected]>
+
+Some files in the tests directory are:
+
+  Copyright 2004, 2008 Bob Proulx <[email protected]>
+
+The two-clause BSD copyright licence applying to all the above files is:

+  LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY
+  OUT OF THE USE OF THIS SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF
+  SUCH DAMAGE.
+
+The three-clause BSD copyright licence for the manual page unifdef.1
+and the portability support code from FreeBSD is below. The fourth
+advertising clause that used to appear between clauses 2 and 3 was
+rescinded by the University of California Berkeley in 1999.
