59: finalise wording, `git show --word-diff` might help with review
- use full names consistently
- use more [[!pkg]] links where possible
- describe FORCE_SOURCE_DATE
- summarise GSoC students' posts
- rewrite helmut's experiment as prose
- move myself to first author
- word wrap so source is easier to read

+ to our source-date-epoch-spec repository explaining `FORCE_SOURCE_DATE`.
+
+ Some upstream build tools (e.g. TeX, see below) have expressed a desire to
+ control which cases of embedded timestamps should obey `SOURCE_DATE_EPOCH`.
+ They were not convinced by our arguments on why this is a bad idea, so we
+ agreed on an environment variable `FORCE_SOURCE_DATE` for them to implement
+ their desired behaviour - neutrally-named, so that at least we can set it
+ centrally. For more details, see the text just linked. However, we strongly
+ urge most build tools *not* to use this, and instead obey `SOURCE_DATE_EPOCH`
+ *unconditionally in all cases*.

-- < helmut> milestone! I got a cross <-> native reproducible dash build up to buildid and data.tar ordering+timestamps!
- < helmut> the big chunk of differences I saw earlier was due the cross toolchain not enabling .init_array/.fini_array
- < h01ger> | helmut: "earlier" or you still see that?
- < helmut> | h01ger: well, I don't know where the archive builds so the buildid varies naturally
- < helmut> | h01ger: and the data.tar/control.tar ordering+timestamps is only fixed in the reproducible toolchain, not the unstable toolchain
-] < helmut> | h01ger: I "fixed" .init_array/.fini_array by adding an autotools preseed for the cross compiler build and since that addition, most elf binary differences have gone away
- < helmut> | relevant commit ids are 12d820314bcb459131eebc55e22a48e545acb0b5 and 39277ab9347848073bcd310f98026177eee2ea66 from rebootstrap.git (both include descriptive long descriptions)
