So you want to modify the text of a PDF by hand...

If you, like me, resent every dollar spent on commercial PDF tools, you might want to know how to change the text content of a PDF without having to pay for Adobe Acrobat or another PDF tool. I didn't see an obvious open-source tool that lets you dig into PDF internals, but I did discover a few useful facts about how PDFs are structured that I think may prove useful to others (or myself) in the future. They are recorded here. They are surely not universally applicable --
the PDF standard is truly Byzantine -- but they worked for my case.

Athenian To whom do you ascribe the authorship of your legal arrangements, Strangers? To a god or to some man? Clinias To a god, Stranger, most rightfully to a god. We Cretans call Zeus our lawgiver; while in Lacedaemon , where our friend here has his home, I believe they claim Apollo as theirs. Is not that so, Megillus? Megillus Yes. Athenian Do you then, like Homer, Cp. Hom. Od. 19.178 . say that
Minos used to go every ninth year to hold converse with his father Zeus, and that he was guided by his divine oracles in laying down the laws for your cities? Clinias So our people say. And they say also that his brother Rhadamanthys,—no doubt you have heard the name,—was exceedingly just. And certainly we Cretans
would maintain that he won this title owing to his righteous administration of justice in those days. Athenian Yes, his renown is indeed glorious and well befitting a son of Zeus. And, since you and our friend Megillus were bo
