+"""Recipe to build CIPD package with sealed Conda environment.
+
+Supposed to be used from manually triggered Buildbot builders. We aren't
+expecting rebuilding this environment often, so setting up and periodic schedule
+is a waste of resources.
+
+To build a new package for all platforms:
+1. Manually trigger all builders by clicking buttons in Buildbot.
+2. Once they all complete, tag the with some release identifier by running:
+    ./cipd set-tag infra/conda_python/scientific/ \
+        -tag=release:<name> \
+        -version=latest
+3. Update Puppet configs to use 'release:<name>' as a version.
