SSVN is a wrapper script for svn to store file permissions in a Subversion repository (along with the versioned file). Permissions and ownership can be restored later. A Unix-like file permissions schema is stored, and GID and UID are stored numerically. This means that this script is not portable to non-Unix systems.
FreeBST ports monitoring is a simple solution for monitoring what has changed in installed ports on a given FreeBSD machine, i.e. what ports were upgraded, installed, or removed. No fancy dependencies: just plain Ruby and shell commands. Results in plain English text are emailed to a given address.
