# Anaconda comes with binaries of system packages (e.g. `openssl`, `curl`).
# Creating shims for those binaries will prevent pyenv users to run those
# commands normally when not using Anaconda.
#
# This is a limited edition of https://github.com/yyuu/pyenv-which-ext
# and it will looks for original `PATH` if there is Anaconda/Miniconda
# installed and the command name is blacklisted.
