Raven's Reference #2: The highly condensed outline of the humanae vitae:

Raven's reference: Parts to the humanae vitae.

Introduction
I: PROBLEM AND COMPETENCY OF THE MAGISTERIUM
2: Note on rate of change, acknowledgement of the changing role of marriage along with pretense that it was always thus.
3: New Questions / need for review.
4: Interpreting the moral law / Establishing that the church has supreme and exclusive authority on this matter.
5: Special Studies / Administrative notes / Point regarding the commission of John XXIII
6: Reply / Why the findings of said commission were thrown out the window.
II: DOCTRINAL PRINCIPLES
7: Section introduction and statement of goals.
8: God's Loving Design / On the sanctity of loving marriage as a divine institution.
9: Married Love / Conditions to qualify: Human, free will, total, faithful until death and, most importantly, reproductive in nature.
"Marriage and conjugal love are by their nature ordained toward the procreation and education of children. Children are really the supreme gift of marriage and contribute in the highest degree to their parents' welfare."
10: Responsible parenthood / definition thereof, with particular emphasis on the role of God rather than man in the decision to reproduce or not.
11: Observing the natural law / On the importance of sex within marriage.
12: Union and procreation / Once again establishing that God made marriage for the purpose of reproduction.
13: Faithfulness to God's Design / The conclusion of the above arguments, in which is it established that all forms of contraception violate the will of God and so are unlawful by nature.
14: Unlawful Birth Control Methods / Moving from the abstract theology to more concrete, practical implications, and preemptive counterargument to the 'lesser evil' argument.
15: Lawful therapeutic means / Exception for medical procedures which cause sterilisation incidentally.
16: Recourse to Infertile Periods / Exception for cycle-timing or rhythm method.
17: Consequences of Artificial methods / In which the church additionally argues against the legalisation of contraception by warning that an inevitable social consequence would be an increase in premarital and extramarital sex, that it may lead to women being seen as mere sexual objects, or that it may be used for coercive population control.
18: Concern of the church / Accepting that this policy will be controversial, and a reminder that the church didn't establish the ban on contraception, but only recognised the one already existing in natural law as revealed by God.
III: Pastoral Directives.
19: Climbing on the high horse.
20: An explanation that struggle will be hard, but this makes it more worthwhile.
21: Value of self-discipline / In support of chastity as a means of birth spacing. Spacing, not prevention. One theme of this document is that it's ok for couples to use non-artificial means to delay having children, so long as they do breed eventually.
22: A call to all those involved in education or politics to promote chastity by prohibiting 'every obscenity in the written word and every form of indecency on the stage and screen' so as to avoid tempting people.
23: Instruction to politicians to ensure the law of their countries complies with this document.
24: Instruction to scientists to direct reproductive science only towards natural rhythms.
25: Instruction to married couples not to use contraception and to have children.
26: Instruction to married couples to instruct others likewise.
27: Instruction to medical professionals not to violate the principles of this doctrine by providing contraception.
28: Instruction to priests to explain this document to followers.
29: Continuation of 28
30: Instruction to bishops to support the priests in their instruction.
31: A reminder that the church doctrine is not to be questioned.
