-
-Features
-========
-Python-scss has most of the funcitonality in Sass SCSS_ 3.2 and more. It supports:
-
-* **Nested rules**
-* **Keyword arguments**
-* **Mixins**: ``@mixin``, ``@include``
-* **Functions**: ``@function``, ``@return``
-* **Inheritance**: ``@extend``
-* **Conditions**: ``@if``, ``@else``, ``@if else``
-* **Loops**: ``@for``
-* **Variables**: ``$``, ``@variables``, ``@vars``
-* **Images**: ``image-url``, ``image-width``, ``image-height``, ..
-* **Embedded inline images**: ``inline-image``
-* **Colors handling**: ``adjust-color()``, ``scale-color()``, ``opacify()``/``transparentize()``, ``lighten()``/``darken()``, ``mix()``, ...
-* **Math functions**: ``sin()``, ``cos()``, ``tan()``, ``round()``, ``ceil()``, ``floor()``, ``pi()``, ...
-* **Options**: ``@option compress:true, sort:false;``, ``@option comments:false;``
-* **Compass_ helpers**: ``enumerate``, ``type-of``, ...
-* **Sorting declarations**: in `Zen sorting order`_
-
-.. note::
-   For ``@import`` support you can use zeta-library_, python compass alternative.
-
-   Zeta-library supported ``@import url(path or http)``, but all static files css, scss.
-
-   Also zeta support js import ``require( '../jquery.js' );``. Zeta allow you control all your static files.

-
-Examples
-========
-
-#. **Nested Rules**
-    Example::
-
-	.selector {
-	    a {
-	        display: block;
-	    }
-	    strong {
-	        color: blue;

-
-        .selector strong {
-            color: blue}
-
-
-#. **Variables**
-    Example::
-
-        $main-color: #ce4dd6;
-        $style: solid;
-        $side: bottom;
-        #navbar {
-            border-#{$side}: {
-            color: $main-color;
-            style: $style;
-            }
-        }
-
-    ...produces::
-
-        #navbar {
-            border-bottom-color: #ce4dd6;
-            border-bottom-style: solid}
-
-#. **Mixins**
-    Example::
-
-        @mixin rounded($side, $radius: 10px) {
-            border-#{$side}-radius: $radius;
-            -moz-border-radius-#{$side}: $radius;

-        #footer { @include rounded(top, 5px); }
-        #sidebar { @include rounded(left, 8px); }
-
-    ...produces::
-
-        #navbar li {
-                -moz-border-radius-top: 10px;
-                -webkit-border-top-radius: 10px;
-                border-top-radius: 10px}
-
-        #footer {
-                -moz-border-radius-top: 5px;
-                -webkit-border-top-radius: 5px;
-                border-top-radius: 5px}
-
-        #sidebar {
-                -moz-border-radius-left: 8px;
-                -webkit-border-left-radius: 8px;
-                border-left-radius: 8px}
-
-#. **Extend** (using `@extend`)
-    Example::
-
-        .error {
-            border: 1px #f00;
-            background-color: #fdd;
-        }
-        .error.intrusion {
-            background-image: url("/image/hacked.png");
-        }
-        .seriousError {
-            @extend .error;
-            border-width: 3px;
-        }
-
-    ...produces::
-
-        .error, .seriousError {
-            background-color: #fdd;
-            border: 1px #f00}
-
-        .error .intrusion, .seriousError .intrusion {
-            background-image: url('/image/hacked.png')}
-
-        .seriousError {
-            border-width: 3px}
-
-#. **Interactive mode**
-    Example::
-
-	$ python scss.py --interactive
-	>>> 25px + 1.5em
-        44.5px
-        >>> lighten(rgba(130,130,130,.4),10%)
-        rgba(155,155,155,0.40)
