Atom.io package which helps to extract information from photoshop layers.
It's very early version so it only collects css information, below is all supported css properties:
width height top ( in psd document ) bottom ( in psd document ) font-size font-family font-weight color ( rgb/rgba ) line-height background-color ( rgb/rgba ) background-image: linear-gradient ( not tested with complex gradients ) text-shadow box-shadow opacity border border-radius text-transform ( uppercase only )
