-// Component updates can be either differential updates or full updates.
-// Full updates come in CRX format; differential updates come in CRX-style
-// archives, but have a different magic number. They contain "commands.json", a
-// list of commands for the patcher to follow. The patcher uses these commands,
-// the other files in the archive, and the files from the existing installation
-// of the component to create the contents of a full update, which is then
-// installed normally.
-// Component updates are specified by the 'codebasediff' attribute of an
-// updatecheck response:
-//   <updatecheck codebase="http://example.com/extension_1.2.3.4.crx"
-//                hash="12345" size="9854" status="ok" version="1.2.3.4"
-//                prodversionmin="2.0.143.0"
-//                codebasediff="http://example.com/diff_1.2.3.4.crx"
-//                hashdiff="123" sizediff="101"
-//                fp="1.123" />
-// The component updater will attempt a differential update if it is available
-// and allowed to, and fall back to a full update if it fails.
-//
-// After installation (diff or full), the component updater records "fp", the
-// fingerprint of the installed files, to later identify the existing files to
-// the server so that a proper differential update can be provided next cycle.
