套件：env-assert（0.010-1）

tool to ensure that the environment variables match expectations

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.
