Optional installation scripts
Your package can use
three types of installation scripts,
although no scripts are required.
Many of the tasks executed in a pre-UNIX System V Release 4
installation script are now accomplished automatically by
pkgadd(ADM).
However, you can use
scripts with a UNIX System V Release 4 package to perform customized actions.
An installation script must be executable by sh (for example,
a shell script or executable program).
The three script types are the request script (solicits installer input),
class action script (defines a set of actions to perform on a group of
objects), and the procedure script (defines actions that will occur at
particular points during installation).
Packaging scripts are described in detail in ``The installation scripts''. Example scripts can be found in the case studies.
