These files are maintained for Serena Deployment Automation (SDA). A corresponding directory structure must be created for each release and the files updated as necessary to point to the corresponding current content. 

index.html is the main online Help link. This simply redirects to the Doc Center sda page, but could point anywhere we decided for a particular release.

stats.html points to the SDA online Help topic for the statistics gathering feature. This is linked to the More Info link from the page that pops up the first time someone logs into SDA (asking them for permission to capture stats) and thereafter for reminders.

updates.html points to information about SDA updates.
