8551 + can be found in th available file.

8554 + reconstruct a .ipk from an installed package, (ie. for beaming
8555 + from one handheld to another). So, maybe we actually want a few
8556 + more fields here, (depends, suggests, etc.), so that that would
8557 + be guaranteed to work even in the absence of more information
8558 + from the available file.
8559 +
8560 + 28-MAR-03: kergoth and I discussed this yesterday. We think
8561 + the essential info needs to be here for all installed packages
8562 + because they may not appear in the Packages files on various
8563 + feeds. Furthermore, one should be able to install from URL or
8564 + local storage without requiring a Packages file from any feed.

11118 + are reused among different packages -- for all such packages we
11119 + should move from "char *"s to some atom datatype to share data
