Re: Devel::Cover for Dummies

[Hue-Bond]

If you use Module::Build, there's already a ./Build target that does the coverage for you. This is an example of a brand new module bootstrapped using Module::Starter's module-starter utility:

$ module-starter --module Foo --mb --author "some 1" --email 'some1@ex
+ample.com'
Created starter directories and files
$ cd Foo
$ perl Build.PL
