+Required tools
+--------------
+
+The  use of  the  Heptagon compiler  by  itself does  not require  any
+additional tools. However,  the usual use involves a  compiler for the
+generated code (e.g., gcc for C generated code, or javac for Java).
+
+The  tools below  are  optional or  are  related to  some subparts  of
+Heptagon:
+- The  graphical display tool  sim2chro can  be obtained  from Verimag
+  [1]. It can be used together with the graphical simulator hepts.
+- The  Sigali  tool [2]  for  model-checking  and discrete  controller
+  synthesis  is mandatory  for the  use  of contracts.  Sigali can  be
+  downloaded on the BZR website : http://bzr.inria.fr.
+
+
+
+Compilation and installation
+----------------------------
+
+* Required libraries and tools for the compilation
+
+The compilation of the Heptagon compiler requires:
+- OCaml [3] (version >= 3.11), and the ocamlbuild and ocamlfind tools
+- the Menhir [4] parser generator
+- the ocamlgraph [5] library.
+
+The  compilation of  the  Heptagon simulator  (optional) requires  the
+LablGTK2 [6] library.
+
+
+* Compilation
+
+Once the  compiler is downloaded  and untarred, go into  the heptagon/
+directory and type :
+
+$ ./configure && make
+
+This command will build the compiler, optionally the simulator (if the
+LablGTK2 library is found), and the standard library.
+
+
+* Installation
+
+After  the  compilation, or  the  download  and  untar of  the  binary
+distribution, go into the heptagon/ directory and type :
+
+$ make install
+
+By default, this will install the binaries (heptc and hepts) into
+/usr/local/bin and the standard library into
+/usr/local/lib. Consider the configure script options
+(./configure --help) for other specific needs.
