The homepage: the logotype, one example, and the manual as a submodule

index.sz shows the logotype, says in a sentence what Bjolang is, shows a
short program (a union, an exhaustive match, a loop), and links to the
manual and its library reference. It has no menu: (listing? #f).

manual/ is BjoManual as a git submodule, served as a folder of the site.
_resources/glasnost.css centres the logotype and keeps it to the column.
glasnost's page cache is ignored.
