 [![Build Status](https://travis-ci.org/mgreter/sass2scss.svg?branch=master)](https://travis-ci.org/mgreter/sass2scss)
 
-It may just work or is probably horribly broken!
+C++ tool/library to convert indented sass syntax to the newer scss syntax. This
+was initially a port of a previous perl implementation. Its primary intention
+was to bring indented sass syntax support to [`libsass`](https://github.com/hcatlin/libsass).
+`sass2scss` is included in `libsass` since [version 2.0](https://github.com/sass/libsass/releases/tag/v2.0).
 
-C++ port of https://github.com/mgreter/OCBNET-CSS3/blob/master/bin/sass2scss.
-This implementation is currently far ahead of the previous perl implementation!
+Unit Tests
+==========
 
-Converts old indented sass syntax to newer scss syntax. My C++ is very rusty so it may
-contain obvious errors and memory leaks. I only tested some basic examples from
-http://sass-lang.com/documentation/file.INDENTED_SYNTAX.html. The scripts reads from STDIN
-and writes to STDOUT, so you should be able to pipe sass files to scss processors.
+I added around 60 unit tests for `sass2sccs` to the `libsass` perl binding
+[`CSS-Sass`](https://github.com/mgreter/CSS-Sass/blob/master/t/05_sass2scss.t).
 
-Added some unit tests for sass2scss to https://github.com/mgreter/CSS-Sass.

+`--pretty` can be repeated up to 3 times to add even more linefeeds (lf).
+
+- 0: Write everything on one line (`minimized`)
+- 1: Add lf after opening bracket (`lisp style`)
+- 2: Add lf after opening and before closing bracket (`1TBS style`)
+- 3: Add lf before/after opening and before closing (`allman style`)
+
+The `listp style` is the only output style that should not alter the line count
+of the input file. This is the best option if you still want to use `source-maps`,
+since it should only change the source by a few inserted chars. So far
+`sass2sccs` does not produce source-maps and `libsass` will not be able to
+produce 100% accurate `source-maps` for indented sass syntax input files!
