It could be useful to have a configurable option so that whenever a
package is installed, all scripts in a set directory would be run.

Maybe a directory called /usr/pkg/libexec/misc-post-install-scripts/ and
each script will be ran.

A script could be for sending an email to all users to let them know about
new software. A script could be used for (permanent) logging that a
package was installed. A script could be used to compare a list of old
packages with new packages. A script could do whatever an admin thinks
would be useful each time a package was installed.

Anyways, I want to use it so it could have symlinks to scripts used for
automatically regenerating menus.

What do you think?

Any suggestions where should the directory be located?

Is "RUN_MISC_POST_INSTALL_SCRIPTS" an okay option name?
