  In this file I use <LEDA> to denote the path name of the LEDA main 
  directory. It should contain the following files and subdirectories: 
  
  readme                    information about LEDA
  install.os                this file
  changes  (please read !)  most recent changes
  compiler (please read !)  list of compilers, problems, and required flags
  fixes                     bug fixes since last release
  incl\                     LEDA include directory
  src\                      LEDA source files
  prog\                     example programs
  man\                      user manual (TeX)
  config\                   configuration directory


  LEDA has been successfully compiled unter OS/2 with Watcom C++ (wcc), 
  and EMX (g++).



1. Configure Makefiles
----------------------
  Go to the <LEDA> directory and call the "config.bat" batch file
  to configure the make files to work with your compiler:
  watcom:  config wcc
  emx:     config emx


2. Compiling the Libraries
--------------------------
   You have to make the following libraries:

   libl.lib      main   library (libL.a )
   libg.lib      graph  library (libG.a )
   libp.lib      plane  library (libP.a )
   libwx.lib     graphics library (libWx.a)

   Go to <LEDA> and call the batch file "make_lib".  


3. Installation of Headers and Libraries
----------------------------------------
  All LEDA header files are in the directory  "<LEDA>\incl\leda". You have 
  to create a directory "leda" in the C++ default include directory and 
  copy all files and subdirectories from "<LEDA>\incl\leda" to this directory.
  Then move all libraries <LEDA>\lib*.lib to the C++ default library directory.


4. Compiling and Linking Application Programs
---------------------------------------------
   Use the libraries as follows to compile and link programs
   (see section 1.9 of the user manual):

   For programs using basic data types (<LEDA>\prog\basic):

   wcl386 -cc++ -zq -x -k32k  prog.c libl.lib 
   gcc    -xc++               prog.c -lL -lm -liostream


   For programs using graph data types (<LEDA>\prog\graph):

   wcl386 -cc++ -zq -x -k32k  prog.c libg.lib libl.lib 
   gcc    -xc++               prog.c -lG -lL -lm -liostream


   For programs using geometric data types (<LEDA>\prog\plane):

   wcl386 -cc++ -zq -x -k32k  prog.c libp.lib libg.lib libl.lib 
   gcc    -xc++               prog.c -lP -lG -lL -lm -liostream



   For programs using geometric data types and windows (<LEDA>\prog\demo):

   wcl386 -cc++ -zq -x -k32k  prog.c libp.lib libg.lib libl.lib libwx.lib 
   rc leda.res prog.exe

   gcc  -xc++ -zq -k32k -bt=os2v2_pm  prog.c -lP -lG -lL -lWx -lm -liostream
   emxbind -bpq -rleda.res /emx/bin/emxl prog.pm
