mk/TODO.md

Short-term

* Unit tests.
* Expanding regex matches in targets.
* Dummy rule for multiple explicit targets
* Expand `$newprereq`.
* Expand `$alltargets`.
* Man page.
* Namelist syntax.
* Environment variables.

Long-term

* Nicer syntax for alternative-shell rules.
* An attribute to demand n processors for a particular rule. This way
  resource hog rules can be run on their own without disabling parallel
  make.
* A switch that prints the rules that will be executed and prompts to user
  to do so. I often find myself doing `mk -n` before `mk` to make sure my
  rules aren't bogus.
