Scan the FreeBSD ports collection and print one-line summary for each port
The FreeBSD ports collection is a skelton of installable software on a local FreeBSD machine. This small utility lets you scan the collection by category, to find out what software is available in that category. Call the script portinfo.py.
A deeper explanation of the script can be found here.
