+# CI that:
+#
+# * checks for a Git Tag that looks like a release
+# * creates a Github Release™ and fills in its text
+# * builds artifacts with cargo-dist (executable-zips, installers)
+# * uploads those artifacts to the Github Release™
+#
+# Note that the Github Release™ will be created before the artifacts,
+# so there will be a few minutes where the release has no artifacts
+# and then they will slowly trickle in, possibly failing. To make
+# this more pleasant we mark the release as a "draft" until all
+# artifacts have been successfully uploaded. This allows you to
+# choose what to do with partial successes and avoids spamming
+# anyone with notifications before the release is actually ready.

+# This task will run whenever you push a git tag that looks like a version
+# like "v1", "v1.2.0", "v0.1.0-prerelease01", "my-app-v1.0.0", etc.
+# The version will be roughly parsed as ({PACKAGE_NAME}-)?v{VERSION}, where
+# PACKAGE_NAME must be the name of a Cargo package in your workspace, and VERSION
+# must be a Cargo-style SemVer Version.
+#
+# If PACKAGE_NAME is specified, then we will create a Github Release™ for that
+# package (erroring out if it doesn't have the given version or isn't cargo-dist-able).
+#
+# If PACKAGE_NAME isn't specified, then we will create a Github Release™ for all
+# (cargo-dist-able) packages in the workspace with that version (this is mode is
+# intended for workspaces with only one dist-able package, or with all dist-able
+# packages versioned/released in lockstep).
+#
+# If you push multiple tags at once, separate instances of this workflow will
+# spin up, creating an independent Github Release™ for each one.
+#
+# If there's a prerelease-style suffix to the version then the Github Release™
+# will be marked as a prerelease.
