    Windows batch script to install locally-saved Python packages into a virtual environment

A hacky script to install Python packages from local wheels / tarballs.
pip should do this by retrieving remote files, but if you're behind a firewall, you can use this instead.

Find and download packages - ideally platform-specific wheel (.whl) files from: https://pypi.python.org/pypi
set the path and name of your desired venv on line 6.
package_names_in_order.txt lists files in a specific order, to enable installing requirements in the correct dependency order.
/packages/ subdirectory (located relative to the .bat script dir) can contain anything pip accepts: .whl; .tar.gz; ...
If you don't require a specific installation order, you can just use (note this is only for .whl files):
for %%f in ( %~dp0\packages\*.whl ) do ( echo "installing %%~f" pip install %%~f )
in place of the package_names_in_order.txt line.


## install_python_packages.bat
REM    Windows batch script to install local Python packages into a virtual environment.
REM    Alongside the script should be "sources" and "packages" subdirectories.
REM    'sources' can contain unzipped folders, each containing a 'setup.py' file;
REM    'packages' can contain anything acceptable for pip install. (*.whl; *.tar.gz)
REM    User should supply 1 argument, the new virtual env's name.
