NAME
       order - package installation order description file

DESCRIPTION
       The package installation order file, .order, is an ASCII file specifying the order in which packages must be installed  based on their pre-
       requisite dependencies.  Any  package with prerequisite dependencies must be installed  after any  packages  it  lists  as  a  prerequisite
       dependency in its depend file.

       A .order file is required for the OS product. The .order file must reside in the top-level directory containing the product.

       The  ordering is specified as a list of package identifiers, from the first package to be installed to the last, one package identifier per
       line.

NOTES
       The depend file supports incompatible and reverse  dependencies.  These dependency types are not recognized in the order  file.
