The package in this case study uses optional information files to define package compatibilities and dependencies, and to present a copyright message during installation.
This case study demonstrates the following techniques:
Using the copyright file
Using the compver file
Using the depend file
For more information on these files, see Creating Information Files.
To meet the requirements in the description, you must:
Create a copyright file.
A copyright file contains the ASCII text of a copyright message. The message shown in the sample file is displayed on the screen during package installation.
Create a compver file.
The pkginfo file shown in the next figure defines this package version as version 3.0. The compver file defines version 3.0 as being compatible with versions 2.3, 2.2, 2.1, 2.1.1, 2.1.3 and 1.7.
Create a depend file.
Files listed in a depend file must already be installed on the system when a package is installed. The example file has 11 packages which must already be on the system at installation time.
