+lib3mf is a C++ implementation of the 3D Manufacturing Format file
+standard.
+
+It provides 3MF reading and writing capabilities, as well as conversion
+and validation tools for input and output data.  lib3mf runs on Windows,
+Linux and MacOS and offers a clean and easy-to-use API in various
+programming languages to speed up the development and keep integration
+costs at a minimum.
+
+As 3MF shall become an universal 3D Printing standard, its quick
+adoption is very important. This library shall lower all barriers of
+adoption to any possible user, let it be software providers, hardware
+providers, service providers or middleware tools.
+
+The specification can be downloaded at http://3mf.io/specification/.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
