pkgng is a binary package manager written from scratch for FreeBSD.

pkgng is built on top of a new libpkg, which allow to deal to the database of

installed packages, to deal with remote repositories, manage packages: creation,

installation gathering informations, registrating new ports.

features supported are or will be :

- smooth integration with bsd.port.mk (see ports/bsd.port.mk.patch) which allow

  to have a bsd.port.mk which deal with both pkg_install and pkgng.

- the register command can analyse elf files when registering a new port to

  discover forgotten dependency if necessary.

- the register command has to mode available : when dealing with old fashion

  ports it just registers the package, in new mode it does everything that would

  have been done by pkg add when installing the package : should messages,

  executing post-install, executing @exec etc.

- pkg add supports two mode : the old fashion one (no real upgrade support) and

  new one: upgrade scripts supported.

- new scripts supported +PREINSTALL +POSTINSTALL, +PREDEINSTALL, +POSTDEINSTALL,

  +PREUPGRADE, +POSTUPGRADE as well as the old fashion scripts : +INSTALL

  +DEINSTALL +UPGRADE

- new +MANIFEST (plist-like format) which new metadatas : options, arch, os

  version, etc. files aren't listed there anymore (no need to have two times the

  same information).

- pkgng supports supports checking arch of the package which means that users

  won't be able to install sparc64 binary package into amd64 machines.

- a special architecture "noarch" allows to specify when a package can be used

  on every architecture.

- @dirrm and @dirrmtry are now deprecated, pkgng can discover itself which

  directory to remove.

- new repository (apt-like feature)

- real support for reverse dependency (no ugly +REQUIRED_BY)

- test unit (libcheck) on libpkg.
