-* Common Workflow Language (CWL)
+To run CWL definitions you can install tools in a Guix environment (avoiding
+Docker). Say you need mafft in a workflow
+
+#+begin_src sh
+    ~/guix-bioinformatics$ env GUIX_PACKAGE_PATH=.:../guix-past/modules/ ~/.config/guix/current/bin/guix environment \
+       guix --ad-hoc cwl-runner mafft
+#+end_src
 
-Install the common workflow language tool cwltool with
+in the new shell you should be able to find both CWL and MAFFT:
+
+#+begin_src sh
+ls $GUIX_ENVIRONMENT/bin/cwl*
+/gnu/store/bhfc5rk29s38w9kgcl4zmcdlh369y9f9-profile/bin/cwl-runner
+/gnu/store/bhfc5rk29s38w9kgcl4zmcdlh369y9f9-profile/bin/cwltool
+ls $GUIX_ENVIRONMENT/bin/mafft
+/gnu/store/bhfc5rk29s38w9kgcl4zmcdlh369y9f9-profile/bin/mafft
+#+end_src
+
+The paths can be loaded into the shell with
+
+: source $GUIX_ENVIRONMENT/etc/profile
+
+* Module system
+
+For those who think they need modules: install the module environment
+with
 
 #+BEGIN_SRC bash
     guix pull
-    guix package -i python2-cwltool
+    guix package -i environment-modules
 
-    cwtool --version
-      1.0.20150916041152
+    modulecmd --version
+      VERSION=3.2.10
+      DATE=2012-12-21
 #+END_SRC
 
+Note that GNU Guix supercedes module functionality!
