+Requirements
+------------
+You will need a C++11 compiler. (gcc 3.3.6 or newer is recommended).
+I use gcc 6.1.0 and 4.1.2, but the code should compile with any standards
+compliant compiler.
+Gcc is available at http://gcc.gnu.org.
+
+POSIX compliant versions of diff and grep are required for zdiff and zgrep.
+
+(Option -L of zgrep fails (prints wrong results, returns wrong status, and
+even hangs) when using GNU grep versions 3.2 to 3.4 inclusive because of a
+wrong change in the exit status of grep, which was reverted in GNU grep 3.5).
+
+Compressors for bzip2, gzip and lzip formats are required to run the tests.
+
+If you are installing zutils along with GNU gzip and want to keep the
+gzip scripts, the recommended method is to configure gzip as follows:
+
+   ./configure --program-transform-name='s/^z/gz/'
+
+This renames, at installation time, the gzip scripts and man pages to
+'gzcat', 'gzcat.1', etc, avoiding the name clashing with the programs
+and man pages from zutils.
+
+
+Procedure
+---------
+1. Unpack the archive if you have not done so already:
+
+	tar -xf zutils[version].tar.lz
+or
+	lzip -cd zutils[version].tar.lz | tar -xf -
+
+This creates the directory ./zutils[version] containing the source from
+the main archive.
+
+2. Change to zutils directory and run configure.
+   (Try 'configure --help' for usage instructions).
+
+	cd zutils[version]
+	./configure
+
+3. Run make.
+
+	make
+
+4. Optionally, type 'make check' to run the tests that come with zutils.
+
+5. Type 'make install' to install the programs and any data files and
+   documentation.
+
+   Or type 'make install-compress', which additionally compresses the
+   info manual and the man pages after installation.
+   (Installing compressed docs may become the default in the future).
+
+   You can install only the programs, the info manual, or the man pages by
+   typing 'make install-bin', 'make install-info', or 'make install-man'
+   respectively.
+
+
+Another way
+-----------
+You can also compile zutils into a separate directory.
+To do this, you must use a version of 'make' that supports the variable
+'VPATH', such as GNU 'make'. 'cd' to the directory where you want the
+object files and executables to go and run the 'configure' script.
+'configure' automatically checks for the source code in '.', in '..', and
+in the directory that 'configure' is in.
+
+'configure' recognizes the option '--srcdir=DIR' to control where to
+look for the sources. Usually 'configure' can determine that directory
+automatically.
+
+After running 'configure', you can run 'make' and 'make install' as
+explained above.
