That page includes information about GDB mailing lists (an announcement
mailing list, developers discussion lists, etc.), details on how to
access GDB's CVS repository, locations for development snapshots,
preformatted documentation, and links to related information around
the net. We will put errata notes and host-specific tips for this release
on-line as any problems come up. All mailing lists archives are also
browsable via the web.
