## The Grist source can be extended. This is a stub that can be overridden
## from command line, as:
##   docker buildx build -t ... --build-context=ext=<path> .
## The code in <path> will then be built along with the rest of Grist.

# settings, you can get sandboxing as follows:
#   docker run --env GRIST_SANDBOX_FLAVOR=gvisor -p 8484:8484 -it <image>
