"""Combine all sheets referred to a given CSS *proxy* sheet

into a single new sheet.

- no ``url()`` values are adjusted so currently when using relative references

  for e.g. images it is best to have all sheets in a single folder 

- in @import rules only relative paths do work for now but should be used

  anyway

- messages are send to stderr

- output to stdout.

Example::

    csscombine sheets\csscombine-proxy.css -m -t ascii -s utf-8

        1>combined.css 2>log.txt

results in log.txt::

    COMBINING sheets/csscombine-proxy.css

    USING SOURCE ENCODING: css

    * PROCESSING @import sheets\csscombine-1.css

    * PROCESSING @import sheets\csscombine-2.css

    INFO    Nested @imports are not combined: @import "1.css";

    SETTING TARGET ENCODING: ascii

and combined.css::

    @charset "ascii";@import"1.css";@namespaces2"uri";s2|sheet-1{top:1px}s2|sheet-2{top:2px}proxy{top:3px}
