      Python 3.4.1

      The Python programming language version 3.

      http://www.python.org


      A lean build of python 3.4.1. 
      It contains the zlib and sqlite3 modules as the only stdlib modules with 
      external dependencies (handled in here by depending on package_zlib_1_2_8 
      and package_sqlite_3_8_3). 
      
      In particular, this build does not compile Python's ssl module (which 
      would cause dependency on openssl and, in turn, on Perl).
      
      This means that **the pip installation tool will not be available with 
      this build** !! 
      
      For a full build (including the ssl module) look at 
      https://toolshed.g2.bx.psu.edu/view/jankanis/package_python3_4 
      written by jankanis, of which this package is a shameless plagiarism. 

      This version of Python includes a built-in virtual environment manager. 
      To create a Python 3 virtual env, include the following actions in your 
      tool_dependencies.xml, e.g. for a package MY_TOOL_venv:

      &lt;action type="set_environment_for_install"&gt;
        &lt;repository name="package_python3_zlib_dependent_1_0" owner="wolma"&gt;
          &lt;package name="python3" version="3.4.1" /&gt;
        &lt;/repository&gt;
        &lt;!-- other install time dependencies --&gt;
      &lt;/action&gt;

      &lt;action type="shell_command"&gt;        
        
        # Create virtual environment MY_TOOL_venv
        # pip cannot be used for installation because it depends on ssl, 
        # which this build does not provide
        
        pyvenv --without-pip $INSTALL_DIR/MY_TOOL_venv
        
        # install python packages
        # assuming you are in the download directory of the package
        
        $INSTALL_DIR/MY_TOOL_venv/bin/python3 setup.py install 
      &lt;/action&gt;
      
    For an example of how this could used by a package look at the 
    tool_dependencies file of:
