Hi,

i really like your simple approach for env configuration and also the possibility to easily print the env variables.
But i'm not that fully happy with the multiline format for the env variables and currently its pretty hard to adjust it.
So maybe it would be useful to have a possibility to pass an own format for the description lines like

"$1 [$2] - $3 (default $4)"

which would be create an output like this

TEST_ENV [string] - This is a test env variable (default "test")

Another maybe more easier approach to implement would be to add an method which returns the parsed metadata so it could be used to print using an own format.

Thanks
