Remark: Starting with AGD version 1.2, the commercial version of AGD is 
integrated in a LEDA package. The following procedures therefore are an 
extension of the installation procedure for LEDA.

1. Files and Directories
------------------------

   To compile and link your programs with AGD and LEDA should contain 
   at least the following files and subdirectories:

     AGD/Install/unix.txt          this file                   
     Install/unix.txt              installation and usage of LEDA
     incl/                         the AGD and LEDA include directory
     libAGD.a (libAGD.so)          AGD library 
     libL.a (libL.so)              LEDA basic library
     libG.a (libG.so)              LEDA graph library
     libG2.a (libG2.so)            LEDA semi-dynamic graph library
     libP.a (libP.so)              LEDA plane geometry library
     libD3.a (libD3.so)            LEDA 3D geometry library
     libW.a (libW.so)              LEDA window library
     libGeoW.a (libGeoW.so)        LEDA GeoWin library

   Static libraries have extension .a.  If shared libraries are provided
   they have extension .so.


2. Preparations
---------------

   Unpacking the AGD/LEDA distribution file 
   (LEDA-<ver_leda>-AGD-<ver_agd>-<sys>-<cc>.zip or 
   LEDA-<ver_leda>-AGD-<ver_agd>-<sys>-<cc>.tgz) will create the LEDA/AGD root 
   directory "LEDA-<ver_leda>-AGD-<ver_agd>-<sys>-<cc>". 
   You might want to rename it or to move it to some different place. 
   Let <leda-agd-root-path> denote the final complete path name of the 
   LEDA/AGD root directory.

   Now you have to modify your environment as follows:

   a)  LEDAROOT:
       set the the environment variable LEDAROOT to <leda-agd-root-path>

       csh/tcsh:   setenv LEDAROOT <leda-agd-root-path>

       sh/bash:    LEDAROOT=<leda-agd-root-path>
                   export LEDAROOT

   b)  Command Search Path:
       include $LEDAROOT/Manual/cmd into your command search path 
       (environment variable path (csh) or PATH (sh)) and call "rehash" (if 
       required by your system).

   c)  Shared Libraries:   (for solaris, linux, irix, osf1)
       If you are planning to use shared libraries include $LEDAROOT into 
       the LD_LIBRARY_PATH search path. Then goto $LEDAROOT and type 
       "make shared". This will construct the shared libraries libAGD.so, 
	   libL.so, libG.so, libG2.so, libP.so,libGeoW.so, libW.so, and libD3.so.


3. Compiling and linking application programs
---------------------------------------------

   a) Use the -I compiler flag to tell the compiler where to find the 
      AGD and LEDA header files:

      CC (g++) -I$LEDAROOT/incl -c file.c

   b) Use the -L compiler flag to tell the compiler where to find the 
      libraries (libAGD.a/so, libL.a/so, libG.a/so, ...)

      CC (g++)  -L$LEDAROOT file.o  <libs>

      <libs>:  -lAGD -lP -lG -lL -lm           (programs without LEDA windows)
               -lAGD -lW -lP -lG -lL -lX11 -lm (programs with LEDA windows)

      If using windows on solaris systems you might have to link with the 
      system socket library and the network services library as well:
      CC (g++)  ... -lAGD -lW -lP -lG -lL -lX11 -lsocket -lnsl -lm

   c) Compile and link simultaneously with

      CC (g++)  -I$LEDAROOT/incl -L$LEDAROOT file.c  <libs>

   You may want to ask your system adminstrator to install the header files 
   and libraries in the system's default directories.
   Then you no longer have to specify header and library search paths on the 
   compiler command line.

   Note: - The libraries must be given in the above order.


4. Example programs and demos
-----------------------------

   The source code of all example and demo programs can be found in 
   $LEDAROOT/test and $LEDAROOT/demo. Goto $LEDAROOT/test or 
   $LEDAROOT/demo and type "make" to compile and link all test or demo 
   programs, respectively. 


5. User Manual
--------------

   All manual pages for AGD and LEDA have been incorporated into the 
   corresponding header files. LEDA provides tools 
   (see $LEDAROOT/Manual/MANUAL/README) to 
   extract and typeset the user manuals from these files. 
   To generate a postscript version of the complete LEDA user manual go to 
   $LEDAROOT and type "make man". The resulting file can be found in  
   $LEDAROOT/Manual/MANUAL/MANUAL.ps. To generate the postscript version
   of the AGD user manual go to $LEDAROOT/AGD and type "make man".
   Postscript, PDF, and HTML versions of both manuals are also available at
