env-assert - 0.010-1 main

The envassert script, accompanied by the Env::Assert module, checks that
your runtime environment, as defined with environment variables, matches with
what you want.
.
You can define your required environment in a file.
Default file is .envassert but you can use any file.
.
It is advantageous to use envassert for examnple when running a container. If
you check your environment for missing or wrongly defined environment
variables at the beginning of the container run, your container will fail
sooner instead of in a later point in execution when the variables are
needed.
