Please find attached csstidy-1.4.ebuild. CSSTidy is a CSS parser and optimizer written in C++. The upstream package in zip format wasn't very easy to work with and also had some incompatibilities with current toolchains, so I used the Debian tarball and diff. I suggest app-text/csstidy.

CSSTidy for a long time is not updated. CSS3 support is missing. Why it might be necessary?
We're been using it with a web app using Django Compressor to process CSS files automatically, and since I wrote the ebuild, I thought I'd submit it here in case it was useful to somebody else. What you say makes sense - it's probably of limited interest. Should this bug be closed?
Well I'm interesting since http://stackoverflow.com/questions/3480264/format-css-with-vim-like-in-textmate recommends this.
This project has stopped new development for ten years and better options exist now. Closing this as obsolete.
