+"""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}
+
+or without option -m::
+
+    @charset "ascii";
+    @import "1.css";
+    @namespace s2 "uri";
+    @namespace other "other";
+    /* proxy sheet were imported sheets should be combined */
+    /* non-ascii chars: \F6 \E4 \FC  */
+    /* @import "csscombine-1.css"; */
+    /* combined sheet 1 */
+    s2|sheet-1 {
+        top: 1px
+        }
+    /* @import url(csscombine-2.css); */
+    /* combined sheet 2 */
+    s2|sheet-2 {
+        top: 2px
