       depend - software dependencies file

       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 ver-
       sion. The format of each entry and subsequent instance definition is:

	 type pkg name

       The fields are:

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

			P    Indicates a prerequisite for installation; for example,  the  refer-
			     enced package or versions must be installed.

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

			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  desig-
			     nated  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 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.

       Example 1 Sample of depend file

       Here are the contents of a sample depend file, for  the	SUNWftpr  (FTP	Server)  package,
       stored in /var/sadm/pkg/SUNWftpr/install:

	 P SUNWcar	 Core Architecture, (Root)
	 P SUNWkvm	 Core Architecture, (Kvm)
	 P SUNWcsr	 Core Solaris, (Root)
	 P SUNWcsu	 Core Solaris, (Usr)
	 P SUNWcsd	 Core Solaris Devices
	 P SUNWcsl	 Core Solaris Libraries
	 R SUNWftpu	 FTP Server, (Usr)
