I write a lot of maple code that my advisor uses, and I'm wanting to make it easier for him to use with as little extra work on my side as possible. Most recently I've started using modules to hold the procedures that go together. For example, I may have something like this

Resultants := module()
  description "This uses various methods to find resultants.":
  export UResultant, MacaulayResultant:

  MacaulayResultant := proc(F,vars)
    -- description and code
  end proc:
