argvalidate lets you control its behaviour via two environment variables.
These variables are documented below.
Defines whether argvalidate should raise exceptions on errors (value: 0, default) or whether warnings should be generated (value: non-0).
Note
The unit tests shipping with argvalidate turn off warnings so they can check if the respective exceptions have been raised.
Defines whether argvalidate should generate a warning if a keyword argument has been passed as a non-keyword argument (value: non-0) or not (value: 0, default).
