Add another index checking script to ensure the sanctity of the
package set. More robust than others already in the tree, but a bit crufty as this was mostly written in the Walnut Creek CDROM days. Sponsored by: FreeBSD Mall, Inc.

This program checks the packages INDEX file to verify that the
|
||||
index is correct and that every package needed by sysinstall is
|
||||
included in the index.
|
||||
|
||||
Options
|
||||
|
||||
-help Display usage instructions
|
||||
-s <src dir> Specify the sysinstall source directory. Use
|
||||
this so to make sure every package referenced
|
||||
in the code is in your INDEX
|
||||
-newindex Generate a new index consisting of only those
|
||||
packages that actually exist in pkgdir/All
|
||||
-depends <pkg> Lists all packages in the index that depend
|
||||
on <pkg>.
