+"""Creates a zip archive for the Chrome Remote Desktop Host installer.
+
+This script builds a zip file that contains all the files needed to build an
+installer for Chrome Remote Desktop Host.
+
+This zip archive is then used by the signing bots to:
+(1) Sign the binaries
+(2) Build the final installer
+
+TODO(garykac) We should consider merging this with build-webapp.py.
