+The only exported function is:
 
 * render_ansi(png_file, text, options=None)
-* make_wttr_in_png(png_file)
 
 `render_ansi` is the main function of the module,
 which does rendering of stream into a PNG-file.
 
-The `make_wttr_in_png` function is a temporary helper function
-which is a wraper around `render_ansi` and handles
-such tasks as caching, name parsing etc.
-
-`make_wttr_in_png` parses `png_file` name (the shortname) and extracts
-the weather query from it. It saves the weather report into the specified file.
-
 The module uses PIL for graphical tasks, and pyte for rendering
 of ANSI stream into terminal representation.
-
-TODO:
-
-    * remove make_wttr_in_png
-    * remove functions specific for wttr.in
