Try the following:
Code:
# cd /usr/ports
# make readme
That will generate a
README.html file in every port directory. Then you can just point a web browser at
/usr/ports/README.html and browse through the ports tree, reading about all the different categories, and all the different ports.
It's not the simple synopsis you may be looking for, but it can be quite helpful when just starting out with the ports tree.
