"""Generate report files to view and/or compare (diff) milestones.
Size files are located in a Google Cloud Storage bucket for various Chrome
versions. This script generates various HTML report files to view a single
milesone, or to compare two milestones with the same CPU and APK.
Desired CPUs, APKs, and milestone versions are set in constants below. If
specified by the --skip-existing flag, the script checks what HTML report files
have already been uploaded to the GCS bucket, then works on generating the
remaining desired files.
Size files are fetched by streaming them from the source bucket, then the
html_report module handles creating a report file to diff two size files.
Reports are saved to a local directory, and once all reports are created they
can be uploaded to the destination bucket.
Reports can be uploaded automatically with the --sync flag. Otherwise, they can
be uploaded at a later point.
