Integrating with pkg

[Jim Trigg]

I'm looking to port a utility from Ubuntu, and need to know what hooks 
there are in pkg. I want to port etckeeper, a tool that automates 
version control for /etc (and in our case $PREFIX/etc). Its current 
implementation uses hooks in apt to automatically check in changes when 
a package is installed/updated; I'm wondering what I can do to support 
that functionality (checking in changes when a package or the base 
system is installed/updated) in FreeBSD.

Thanks,
Jim Trigg
