This option is used to point wic to the directory with .env
files containing list of bitbake variables and their values.

If this option is used wic will get bitbake variables from
files instead of parsing 'bitbake -e' output.

The main reason for this is to support new mode, when bitbake
runs wic to produce wic images. In this case wic can't run bitbake
again as it's locked, so it will get variables from .env files.
