Portupgrade is a tool to upgrade installed packages via ports or packages. It upgrades installed packages without reinstalling depending or dependent packages by directly updating the package registry database located under /var/db/pkg, while it can also trace dependency chains up and down to upgrade packages recursively. This package also includes the following utilities: portinstall: Helps you install new ports in a handy way. portcvsweb: Instantly browses a history via CVSweb. portversion: Replaces pkg_version(1), runs much faster and is cooperative with portupgrade(1). portsclean: Cleans ports workdir's, unreferenced distfiles and old and orphan shared libraries. portsdb: Creates binary database from the ports INDEX. ports_glob: Expands ports globs. pkg_deinstall: Wraps pkg_delete(1) and provides extra features. pkg_fetch: Fetches packages from a remote site. pkg_glob: Expands package globs. pkg_which: Checks which package a file came from quickly. pkgdb: Manipulate the package database and interactively fixes most problems in the /var/db/pkg registry.
