>Description:
Packages.txt explains how to use DEPENDS+=, but doesn't explain how to
depend on either or two packages.
>How-To-Repeat:
Try to get mklivecd to use cdrtools-ossdvd if installed rather than
forcing cdrecord, read Packages.txt before posting, and get told the
answer in email.

 Please note that such dependencies should only be updated if a package requires
 a newer pre-requisite, but not to denote recommendations such as security
 updates or ABI changes that do not prevent a package from building correctly.
