The name of a class action script is based on
which class it should operate and
whether those actions should occur during package installation or removal.
The two name formats are:
i.class
operates on pathnames in the indicated
class during package installation
r.class
operates on pathnames in the indicated
class during package removal
For example, the name of the installation script for a class named class1
would be i.class1 and the removal script would be
named r.class1.
