 // Copyright 2014 The Chromium Authors. All rights reserved.

 // 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" />
+//                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.
