Try to delete files

[Nigel Taylor]

Hi all,

Hi, in my years of using freebsd i have collected alot of distfiles in 
the ports tree and i want to free up some space on my harddrive and i 
was wondering is there a command to delete files in the distfiles folder 
that are less than the year 2000?

Or maybe there is a program that deletes all the older releases in the 
distfiles? if someone could help i would be gratefully

Thanks
