The ports-collection of FreeBSD allows users and admins to install applications easily. At the moment are in the ports-collection more than 30.000 ports.
The ports-collection supports always the newest version of an application for FreeBSD-CURRENT and FreeBSD-STABLE. Older versions will not be supported.
Each port contains also all patches of a source code of an application.
To install an application you have to download the source code and unpack it. You have to go to the directory of that port on your PC and do: make install as root.
Each port contains a make-file. It downloads, unpacks and installs the source code and all patches of an application.
