+Installation instructions
 
-Compiling from source code
-
-   The UltraGrid system depends on modified versions of Tcl-8.0 and Tk-8.0
-   which should be included in the distribution. It will not work correctly
-   with the standard Tcl/Uk versions.
-
-   On Unix like systems, you should build the tcl-8.0 and tk-8.0 packages
-   before trying to build UltraGrid:
-
-	cd ../tcl-8.0/unix
-	./configure
-	make
-	cd ../../tk-8.0/unix
-	./configure
-	make
-
-   Once this is complete, return to this directory and compile the
-   UltraGrid system:
-
-	./configure
-	make
-
-   This will detect the characteristics of the build host, compile the
-   system, and run a number of tests. The resulting binary will be the 
-   file "bin/uv".
