 """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.

 Reports can be uploaded automatically with the --sync flag. Otherwise, they can
 be uploaded at a later point.
