Is there a "$ virtualenv env/" missing here? Or how is the virtualenv expected to come into existence?

+Integrate project specific Documentation into the Manual
+PTXdist supports the ability to integrate project specific documentation
+into the final PTXdist manual. To do so, PTXdist handles file replacements and
+additions, while generating the documentation.
+File replacement is working in the same manner like for all other files in
+a PTXdist based project: a local file with the same name superseds a global 
+from PTXdist.
+With this mechanism we can replace existing PTXdist documentation or add new

+In the generic documentation source many text uses variables instead of fixed
+content. These variables are filled with values extracted from the current 
+project prior building the final documentation. Since PTXdist projects are 
+to a defined PTXdist version and toolchain version, this kind of information is
+extracted from the current settings and substituted in the documentation. This
+behaviour ensures the documentaiton includes the project's exact definition to
+external dependencies.
+Refer the PTXdist file ``doc/conf.py`` for more information on variable
