'page is a macro on top of 'htmlpage to create a page with the look&feel of the project site.
'login is something like: (goodcrypt pwd (get-passwd-of-user user)) ('goodcrypt is in files.arc).
"op" means "operation" in my lexicon, and is for /x/... paths, stateful actions. I know,
this is confusing, it's not the same notion than in srv.arc ('defop). But in my mind, even

In srv.arc, the "operations" system is +/- the 'fns* / 'fnids* / 'flink / etc. stuff.
