Ooops, forgot the Bugzilla PR #: 241814

Note 1: Images removed from the English version but still used by translations have been kept until the translations catch up. These images are: share/images/books/dev-model/hats-overview.png, share/images/books/dev-model/maintenance.png, share/images/books/dev-model/orghierarchy.png, share/images/books/dev-model/orghierarchy.sla, share/images/books/dev-model/orghierarchy2.png, and share/images/books/dev-model/proc-releng.png.

Note 2: I think it's OK to include a local copy of https://web.archive.org/web/20121223081637if_/http://www.freebsd.org/ports/growth/status.png in the document, since that image came from the FreeBSD website originally. But IANAL, so take that opinion with appropriate amounts of salt.

For the entire document, please do s/screenreader-friendly/screen-reader friendly/g so that it uses the same verbiage.

737–747

Would it be better to use <note>Refer to the table below for a screen-reader friendly version.</note>?

1481–1490

This would also be a good use of <note>Refer to paragraph below for a screen-reader friendly version.</note>.

1676–1677

Same as above with regard to use of <note></note>.

2463–2464

Yet another instance where <note></note> is useful.

[bcr]

Overall, this is a great addition and update. Thank you.
There are other things that need to be fixed, but that should come in a separate follow-up commit to not blow up this review with more changes.

For this overlong link, you can break it like this:
<link<ENTER
<TAB>xlink...>a<ENTER>
<TAB>primer</link>.

Refer to section 9.8.3. in the primer https://www.freebsd.org/doc/en_US.ISO8859-1/books/fdp-primer/docbook-markup-links.html for details and examples.

Address changes requested by debdrup and bcr.

For debdrup's changes, I didn't use a note, but the textobject-in-mediaobject
method described in section 9.7.3 in
https://www.freebsd.org/doc/en_US.ISO8859-1/books/fdp-primer/docbook-markup-images.html
so as to have that text wind up in the alt= img attribute. (I also didn't
put in ASCII art because 1- my skill for it is minimal, 2- I hear it confuses
screen reader users, and 3- there wasn't any before anyway.)

[debdrup]

Looks good to me now.

are there ~5500 or only ~3000?

As far as I can see from the SVN log, the text has always said 5500, and the image (introduced with r24914 in 2005) 3000. I have no idea which figure is correct. That said, there's a comment a few lines below that says "Lost the script, TODO: recompute the estimate", so perhaps I should do that (with someone else's help) and this time add the script to the repo or as a comment here depending on how long it is. Or maybe that should be a separate commit. What does everyone think?

Looks good to me.

I'd say if we don't have the script anymore, we can create a new one in a separate commit and commit this change with the original number. We can then update it with the more accurate number coming from the new script.

Can a committer take care of it? I'm not one. (Also, reminder: the PR# is 241814 - I forgot it in the initial summary.)
