NAME
     depend - software dependencies file

DESCRIPTION
     depend is an ASCII file used to specify information concern-
     ing software dependencies for a particular package. The file
     is created by a software developer.


     Each entry in the depend file describes  a  single  software
     package.  The instance of the package is described after the
     entry line by giving the package  architecture  and/or  ver-
     sion.  The  format  of  each  entry  and subsequent instance
     definition is:

       type pkg name
       (arch)version
            (arch)version
               ...




     The fields are:

     type             Defines the dependency type. Must be one of
                      the following characters:

                      P    Indicates a prerequisite for installa-
                           tion;   for  example,  the  referenced
                           package or versions must be installed.


                      I    Implies  that  the  existence  of  the
                           indicated package or version is incom-
                           patible.


                      R    Indicates   a   reverse    dependency.
                           Instead  of defining the package's own
                           dependencies,  this  designates   that
                           another  package  depends on this one.
                           This type should be used only when  an
                           old  package  does  not  have a depend
                           file, but relies on the newer  package
                           nonetheless.  Therefore,  the  present
                           package should not be removed  if  the
                           designated old package is still on the
                           system since, if it  is  removed,  the
                           old package will no longer work.

     pkg              Indicates the package abbreviation.


     name             Specifies the full package name.


     (arch)version    Specifies  a  particular  instance  of  the
                      software.  A version name cannot begin with
                      a left parenthesis. The instance specifica-
                      tions,  both  (arch)  and version, are com-
                      pletely optional,  but  each  (arch)version
                      pair  must  begin on a new line that begins
                      with  white  space.  A  null  version   set
                      equates  to  any  version  of the indicated
                      package.
