 based-upon context. Perhaps the most immediate and simple way to set/override a variable for a given graph is 
 simply to use the optional ``--env`` argument when running bonobo from the shell (bash, command prompt, etc). 
 ``--env`` (or ``-e`` for short) should then be followed by the variable name and value using the
-syntax `VAR_NAME=VAR_VALUE`. Multiple environment variables can be passed by using multiple ``--env`` / ``-e`` flags. Additionally, in bash you can also set environment variables by listing those you wish to set before the `bonobo run` command with space separating the key-value pairs (i.e. `FIZZ=buzz bonobo run ...` or `FIZZ=buzz FOO=bar bonobo run ...`).
