+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.

+The three-clause BSD copyright licence for the manual page unifdef.1

+unifdef installation instructions
+---------------------------------
+
+Dependencies:
+ * unifdef is mostly ANSI C, with a few unixisms
+ * unifdefall is a Unix shell script
+ * the manual uses the nroff mdoc macros
+ * the support and test scripts are Unix shell scripts
+
+To build on Unix, type `make`. You can adjust the compilation options
+using the POSIX standard CFLAGS and LDFLAGS make variables.
+
+To install in your home directory, type `make install`
+or to install in /usr type `make prefix=/usr install`.
+See the start of the Makefile for the install location
+variables.
+
+The win32 subdirectory contains build files for MinGW and Visual
+Studio 2010 which make use of the FreeBSD code plus some other
+portability wrappers.
+
+To build with MinGW, type `mingw32-make -f win32/Makefile.mingw`.
+
+Unlike the Unix Makefile, the Windows builds do not automatically
+create or update version.h. The release tar and zip files include a
+pre-generated version.h but the git repository does not. To build from
+a git clone you need a Unix shell environment, which you can get as
+part of GitHub for Windows - http://windows.github.com/
+To update version.h, right-click on the fanf2/unifdef repository and
+select "open a shell here", then type `sh scripts\reversion.sh`.
+
+We assume Unix provides the BSD err.h functions and C99 stdbool.h. The
+FreeBSD subdirectory has copies of err.c and getopt.c for systems such
+as Windows that don't have them built in.

+unifdef - selectively remove C preprocessor conditionals
+
+Written by Tony Finch <dot@dotat.at> - http://dotat.at/prog/unifdef/
+
+The unifdef utility selectively processes conditional C preprocessor
+#if and #ifdef directives. It removes from a file both the directives
+and the additional text that they delimit, while otherwise leaving the
+file alone.
+
+Please see the INSTALL file for installation instructions.
+
+Pre-formatted documentation can be found in unifdef.txt
+
+You can download the latest release tar and zip files from:
+	http://dotat.at/prog/unifdef
+
+You can clone the development repository using:
+	git clone http://dotat.at/git/unifdef.git
+
+I also maintain a copy at http://github.com/fanf2/unifdef
+(Warning: GitHub's zip download is incomplete and unusable.)
+
+Please send bug reports and patches to me via email to the
+address above. Unless you state otherwise, I will assume that
+any contributions are under the two-clause BSD licence. See
+the COPYING file for details.
+
+Thanks to the following people for their contributions:
