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.
