The depend(F) package information file defines software dependencies associated with the package. You can define three types of package dependencies with this file:
The generic format of a line in this file is:
type pkg nameDefinitions for each field are as follows:
P indicates the named package is a prerequisite for installation.
I indicates the named package is incompatible.
R indicates a reverse dependency (the named package requires that this package be on the system).
This last type should only be used when a pre-UNIX System V Release 4 package (that cannot deliver a depend file) relies on the newer package.
Here is an example of this file:
P acu Advanced C Utilities Issue 4 Version 1 P cc C Programming Language Issue 4 Version 1 (386) R vpkg Another Vendor Package
