data ReqStrength

The type for specifying how strictly a requirement should be enforced.

Constructors

Must

A requirement must be satisfied

Should

A requirement should be satisfied, but it is not an error if it cannot be.

May

A requirement should only be satisfied at the user's option. Typically, automated processes will ignore this.

ShouldIfInstalled

Like Should, but looks at packages that are already installed.

MayIfInstalled

Like May, but looks at packages that are already installed.
