v0.6.0

The highlight of this release is the introduction of enums (aka variants or options) which can be used to limit and validate a variable's value.

For example:

Makefile:

define-enum : bmakelib.enum.define( DEPLOY-ENV/development,staging,production )
include define-enum

deploy : bmakelib.enum.error-unless-member( DEPLOY-ENV,ENV )
deploy :
	@echo 🚀 Deploying to $(ENV)...

Shell:

$ make ENV=local-laptop deploy
*** 'local-laptop' is not a member of enum 'DEPLOY-ENV'.  Stop.

$ make ENV=production deploy
🚀 Deploying to production...
