+# Summary: Run an executable with the selected Python version
+#
+# Usage: pyenv exec <command> [arg1 arg2...]
+#
+# Runs an executable by first preparing PATH so that the selected Python
+# version's `bin' directory is at the front.
+#
+# For example, if the currently selected Python version is 2.7.6:
+#   pyenv exec pip install -r requirements.txt
+#
+# is equivalent to:
+#   PATH="$PYENV_ROOT/versions/2.7.6/bin:$PATH" pip install -r requirements.txt
