will add an entry to the available file if there is not an entry there already.

If the package has an entry, the entry will be updated with the information

about this version of the package.

  update avail |   merge avail

When the   update avail option is used, the old information about the packages

in available is replaced by the package information contained in the

file>. This file is found in the top directory of a binary distribution, so Pack

ages files can be found in binary i386/, contrib/, and non free/.

Issuing the command:

dpkg   update avail /home/ftp/stable/binary i386/Packages

will replace the old available file with the contents of the Packages file found

in /home/ftp/stable/binary i386. This option is intended for use when a new

release archive is being used.

The   merge avail adds the Packages file from another binary tree to the list

of available packages. The new information gets combined with the old list,

adding information on new packages to the available file. The following com

mands:

dpkg   clear avail

dpkg   merge avail /home/ftp/stable/binary i386/Packages

dpkg   merge avail /home/ftp/contrib/Packages

dpkg   merge avail /home/ftp/non free/Packages

will create an available file that reflects all three of these areas of the distri

bution archives.
