# Summary: Activate virtual environment

# Usage: pyenv activate <virtualenv>
|
|
# pyenv activate --unset

# Activate a Python virtualenv environment in current shell.
|
|
# This acts almost as same as `pyenv shell`, but this invokes the `activate`
|
|
# script in your shell.
|
|
#
|
|
# <virtualenv> should be a string matching a Python version known to pyenv.
