510 told Zero Install about it by adding a feed. (package) means that this version \
511 is provided by your distribution's package manager, not by Zero Install. \
512 In off-line mode, only cached implementations are considered for use.
514 Arch indicates what kind of computer system the implementation is for, or 'any' \

526 another interface you are using and, in off-line mode, uncached implementations. Unusable \
527 implementations are shown crossed out.
