Packaging of a Web viewer of medical images
Dear Debian Med community,
The Orthanc project has just released a free and open-source Web viewer of medical images that integrates smoothly as a plugin to Orthanc . The Web viewer is based upon Chris Hafey's Cornerstone  and Mathieu Malaterre's GDCM . I feel that this plugin might ease the access to medical images.
I have therefore started to work on a Debian package for this Web viewer, nicknamed "orthanc-webviewer". Please note that I am currently unable to formally file an ITP because of a transient problem with reportbug .
This "orthanc-webviewer" package will have to modify the JSON configuration file "/etc/orthanc/orthanc.json" from the "orthanc" package, by adding options that are only related to the Web viewer. However, the system administrator might have applied local modifications to the original "/etc/orthanc/orthanc.json" in between.
My question is the following: What is the recommended way of "patching" a configuration file, given that this file might be affected by local changes?
Thanks in advance,
