"""build.py -- the starshipos-f18.com XWiki pages, made from the "StarshipOS.com" design canvas.

    site/com/build.py [--release TAG --sums SHA256SUMS]
                           canvas/{Main,Inquiries,TryIt}.dc.html -> {Main,Inquiries,TryIt}.WebHome.xwiki,
                           and with a release, canvas/{Downloads,Documents}.dc.html too

The canvas is the source: its artboards are copied into canvas/ as they are, and this turns each into
one {{html}} block (which needs a page author with script rights). What changes on the way:

  - the accent hole becomes its default colour, and the canvas's links become the wiki's pages
    (Main.dc.html -> /bin/view/Main/, ...) and the real domains (starshipos.org -> starshipos-f18.org);
  - the two images become attachments of Main.WebHome (badge.jpg, captain-bob.jpg -- web-size copies
    of the canvas's uploads);
  - Try it: the drawn console becomes the real one, an iframe of try.starshipos-f18.com;
  - the inquiry form posts to the .org's PublicInquiry, which files it under Inquiries there
    (admin-only, site/org/inquiries); the announcements form, which has no server, sends by e-mail;
  - Downloads and Documents (#126, #157) are built from a release: --release TAG and the release's
    SHA256SUMS fill in [TAG], [RELEASE]/<file> (the file on the Gitea release) and [SHA:<file>].
    Without a release they are not built, and the other pages' links to them are taken out, so
    nothing on the site points at a page that is not there (they go live with alpha.4);

install.sh puts the pages and the images on the wiki.
