A tutorial on D templates

[Philippe Sigaud]

[Cross-posted with D.announce, since it's also an annoucement]

Hello all,

I discovered D a few years ago and, seeing the recent increase in community projects, I
looked for a way to bring my own small part to it.

I quite like D templates and wanted to try LaTeX again, so I decided to bite the bullet
and wrote a tutorial on templates. It's far from finished and most probably full of
mistakes but since it's already quite big, I need some inputs.

It's a Github project, here:

The resulting pdf is there:

If you have any comment, criticism, explanation, what have you, I'm game. What section
should be expanded, what example would be cool, etc. If you see a mistake, do not
hesitate to tell me: it's the first time I put thoughts on paper like this. Github
issues management is far from perfect, but it's usable. Even better would be pull
requests :)

There is an 'Examples' section where I show what can be done with templates and there I
'borrowed' some code posted here, with attribution. I already exchanged with Andrej
Mitrovic (thanks!), but also took some code from Timon Gehr, Simen Kjaeraas, Trass3r
and Jacob Carlborg. Guys, if any of you have a problem with that, tell me so and I'll
take down the code of course. But if any of you could give me some explanation (a small
paragraph or two?) about what your code does, I'll be forever grateful :)

This also extend to anyone who would want to share some template love/lore with the
rest of us.
