+Description:
+sfntly is a C++ library for using, editing, and creating sfnt container based
+fonts (e.g. OpenType, TrueType).  We use it to subset the embedded font in the
+PDF generated in print preview so that the result PDF documents are
+significantly smaller and loaded faster.

Can LICENSE be taken upstream?

You can add a 'License File:' line to README.chromium with the appropriate path
if there's already a LICENSE file there.

The license sits in a different folder upstream and I don't want to copy
unnecessary files (e.g. Java code).  I've added description about this.

+A sfntly.gyp file has been added for building with Chromium.
