Reclaiming disk space was a high priority on my laptop, which has a 4gb 
FreeBSD partition.  So, I wrote a useful shell script for removing all the 
"work" directories in the ports tree (I'm sure someone has already done 
this, but it saves a little bit of time for those people who are not 
fluent in shell scripting).  You'd be surprised how much disk space can be 
freed up by removing unused source code and compiled objects.

Peace,
- Ralf
