+======
+
+Ctypes based module to access libbsd's strvis & strunvis functions.
+
+The `vis` function is the equivalent of strvis.
+The `unvis` function is the equivalent of strunvis.
+All functions accept unicode string as input and return a unicode string.
+
+Constants:
+----------
+
+* to select alternate encoding format
+  `VIS_OCTAL`:      use octal \ddd format
+  `VIS_CSTYLE`:     use \[nrft0..] where appropiate
+
+* to alter set of characters encoded
+  (default is to encode all non-graphic except space, tab, and newline).
+  `VIS_SP`:         also encode space
+  `VIS_TAB`:        also encode tab
+  `VIS_NL`:         also encode newline
+  `VIS_WHITE`:      same as (VIS_SP | VIS_TAB | VIS_NL)
+  `VIS_SAFE`:       only encode "unsafe" characters
+
+* other
+  `VIS_NOSLASH`:    inhibit printing '\'
+  `VIS_HTTP1808`:   http-style escape % hex hex
+  `VIS_HTTPSTYLE`:  http-style escape % hex hex
+  `VIS_MIMESTYLE`:  mime-style escape = HEX HEX
+  `VIS_HTTP1866`:   http-style &#num; or &string;
+  `VIS_NOESCAPE`:   don't decode `\'
+  `VIS_GLOB`:       encode glob(3) magic characters
