Requirements
------------
You will need a C++ compiler and the lzlib compression library installed.
I use gcc 4.9.1 and 4.1.2, but the code should compile with any
standards compliant compiler.
Lzlib must be version 1.0 or newer.
The fast encoder is only available in lzlib 1.7-pre1 or newer.
Gcc is available at http://gcc.gnu.org.
Lzlib is available at http://www.nongnu.org/lzip/lzlib.html.


Procedure
---------
1. Unpack the archive if you have not done so already:

	tar -xf plzip[version].tar.lz
or
	lzip -cd plzip[version].tar.lz | tar -xf -

This creates the directory ./plzip[version] containing the source from
the main archive.

2. Change to plzip directory and run configure.
   (Try 'configure --help' for usage instructions).

	cd plzip[version]
	./configure

3. Run make.

	make

4. Optionally, type 'make check' to run the tests that come with plzip.

5. Type 'make install' to install the program and any data files and
   documentation.

   Or type 'make install-compress', which additionally compresses the
   info manual and the man page after installation. (Installing
   compressed docs may become the default in the future).

   You can install only the program, the info manual or the man page by
   typing 'make install-bin', 'make install-info' or 'make install-man'
   respectively.

   Instead of 'make install', you can type 'make install-as-lzip' to
   install the program and any data files and documentation, and link
   the program to the name 'lzip'.


Another way
-----------
You can also compile plzip into a separate directory.
To do this, you must use a version of 'make' that supports the 'VPATH'
variable, 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.
