+Python Virtual Environments (conda, pyenv)
+==========================================
+
+If your system uses virtual environments to manage different Python versions,
+such as pyenv or anaconda, these tools will add a performance delay to every
+shell prompt.  This delay can be bypassed by explicitly specifying your command
+path.
