This tool is currently used to build components of HL7FHIR implementation guides as used by NHS Digital in England.
The tool is currently created with many features specifically created to meet NHS Digital requirements. Where possible these can be refctored to make them more universally applicable.
The tool is still being developed and changes are exepcted to appear. Initially these will be in "feature" branches.
The master branch will reflect the code currenty used by NHS Digital in their product sets.
Note this project was initially based on a published project created by Furore (also on GitHub - https://github.com/furore-fhir/Fhir.Publication ) This project has extended the project significantly as well as making it work for DSTU2.
