## Gathering shasums of build outputs
After a successful build, the shasums of the build outputs are gathered
into files named `SHA256SUMS`. These files are located in each of the
architecture-specific output directories.
To gather all shasums and output them together to console, for e.g.
inclusion in a Guix pull request comment, run:
``` sh
source contrib/shell/git-utils.bash && uname -m && find guix-build-$(git_head_version)/output/ -type f -print0 | env LC_ALL=C sort -z | xargs -r0 sha256sum
```
