The OpenDocx fork of Open-Xml-Power-Tools. Closely based on maintainer EricWhite's vNext fork (as of June 2021), but includes only .NET Standard 2.0 build target for use in cross-platform scenarios. This version also includes a minor but experimental extension that facilitates document composition, as well as a handful of bugfixes.
