summary: Count snaps per architecture
description: |
  Count snaps by doing a word count of the locally cached list
  of snaps in the store. Run this build on each architecture
  and it will give you each snap with the version set to the
  number of public snaps on that architecture. Roughly.
  You will also get a log file which lists them all.

architectures:
  - build-on: i386
  - build-on: amd64
  - build-on: arm64
  - build-on: armhf
  - build-on: s390x
  - build-on: ppc64el
  - build-on: riscv64
