-Prerequisites
--------------
-
-The RTL source code references the ROC component from Xilinx' unisim
-library. If not already done, you'll have to prepare this library containing
-at least the roc entity and architecture objects.
-
-Decide where to store this library. This could be locally in this directory or
-at some central place where it can be referenced from other projects. I'd
-prefer the latter option.
-
-  $ cd <where unisim lib should be stored>
-
-Prepare the sources for GHDL:
-  $ mkdir src
-  $ cd src
-  $ ghdl --chop <WebPack installation dir>/vhdl/src/unisims/*
-  $ cd ..
-
-Import the sources into the library:
-  $ mkdir unisim_v93
-  $ ghdl -i --work=unisim --workdir=unisim_v93 --std=93 -fexplicit --no-vital-checks --ieee=synopsys src/*
-
-Compile the required component:
-  $ ghdl -m --syn-binding --work=unisim --workdir=unisim_v93 --std=93 -fexplicit --no-vital-checks --ieee=synopsys roc
-  $ rm roc
-    -> not required for library
-
-If you require more components from the unisim library for other projects, you
-can repeat the compile step later on without running through the preparation
-and import steps.
-
+Removed ROC/unisim dependency 16-Jun-2008.
 
 Compiling the example
 ---------------------
 
-Edit ghdl_options.sh and point the variable UNISIM_DIR to the location of your
-newly created unisim library.
+Make all shell scripts executable:
+  $ chmod +x *.sh
+
+On Linux, convert files from DOS format:
+  $ dos2unix *.sh
 
 You need to import the project sources once by running
   $ ./ghdl_import.sh
