Browse source 
* Fix proposal for bug 25151

* Fix proposal for bug 25151 - pip module, pyvenv validation

* Graceful fail when virtualenv_python is defined and virtualenv_command uses the venv module

* Making sure that venv is being used as a modue "-m venv"

* Updating syntax in validations

* Updating syntax in validations - fixing stupid typo "[)"

* Raising an error if virtualenv_command is pyvenv or venv and virtualenv_python is used

* trailing whitespace gone, pyvenv, venv validation and docs update

* cleaning whitespaces from blank lines
