-UI
---
-
-*   Heavily prefer unix filter UI.
-
-    If you can't do it with filtering, it could mean you should
-    split your function anyway.
-
-*   Even function can use dash options and even `usagef()`.
-
-*   Reserved options are
-
-     *  `-q|--quiet`, to turn off verbosity,
-     *  `-v|--verbose`, to turn on verbosity,
-     *  and `-d|--debug` to turn on debug output (stderr).
-
-*   Do not `think()` in functions.
-
-*   Preferred capitalization in messages is:
-
-    *   all small for libs (debug/warn/die)
-
-    *   First cap for scripts
-
-*   Message width:
-
-    *   think/warn/die: try hard to never exceed 72
-
-    *   debug: do what you must
-
-    *   always try to split message to fixed part, colon and  *before* colon and
-        the "data" part after the colon, e.g.:
-
-            file missing: /var/run/media/somebody/some-medium/some-long/path
-
-        instead of:
-
-            file /var/run/media/somebody/some-medium/some-long/path is missing
- 
-        (even if you think that it will be short)

-PRINCIPLES
-----------
-
-Be smart but honest: if you can default, default, otherwise be honest = fail
-
-Don't talk.  `think()` instead.
