------------------------+--------------------------
 This port contains sassc and its dependency libsass.

 Libsass is a C/C++ library implementation with a C API of a sass
 "compiler", generating CSS from SCSS/SASS files.
 Sassc is a command-line tool that uses libsass.

 This provides similar functionality to the ruby sass implementation. But
 sassc is faster and has no big ruby dependency.

 This is my first port. I didn't attach my name as maintainer but I'm OK
 with being marked as maintainer if it helps to have a maintainer and no
 one else wants to.

 Libsass is pretty straightforward. Makes a static library and installs it
 along with header files.

 Sassc needs a patch. Because it assumes it is also in charge of compiling
 libsass. The patch disables that assumption. With the patch, the Makefile
 will assume the library/headers are in place, which they are, because
 libsass is marked as dependency in the sassc Portfile.

 You could create a sassc port without having a separate libsass port. Two
 reasons I didn't: 1. libsass could be useful on its own. 2. I don't know
 how to fetch two different distfiles and extract them in the right
 location etc, this was easier. (:

 Attached are the portfiles and patch.
