NAME
       depend - software dependencies files

DESCRIPTION
       depend is an ASCII file used to specify information concerning
       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 version.  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 installation, for
                            example, the referenced package or versions must
                            be installed.

                       I    Implies that the existence of the indicated
                            package or version is incompatible.

                       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 it
                            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 specifications, both arch and version, are
                     completely optional but must each begin on a new line
                     that begins with white space.  A null version set
                     equates to any version of the indicated package.
