As a  purchaser of the OpenBSD CD-ROM you already have several popular
``packages'', the ``ports'' collection, and some of the ``ports''
source file releases.

Installing applications from the CD-ROM package collection:

	The OpenBSD CD-ROM ships with several applications pre-built
	for various hardware architectures.  The number of applications
	vary according to available disk space.  Check the directory
	2.7/packages/<arch> to see which packages are available for
	your hardware architecture.

	To install one or more of these packages you must
	1) become the superuser (root)
	2) mount the appropriage CD-ROM
	3) use the ``pkg_add'' command to install the software

	Example (in which we use su(1) to get superuser privileges, thus
	you have to be in group "wheel", see the manual page for su(1)).

    $ su
    Password: <enter your root password>
    # mkdir -p /cdrom
    # mount /dev/cd0a /cdrom
    # cd /cdrom/2.7/packages/<arch>
    # pkg_add -v <package-name>
    # <add more packages if desired>
    # umount /cdrom
	
	Your hardware architecture can be determined by issuing
	the command ``arch''.  The response will be something like
	``OpenBSD.sparc''.  ``sparc'' is the architecture.

	Package names are usually the application name and version
	with .tgz appended, e.g. emacs-20.3.tgz

Installing applications from the ftp.openbsd.org package collection:

	All packages have been placed on ftp.openbsd.org in the directory
	pub/OpenBSD/2.7/packages/<arch>/ where <arch> is the supported
	hardware architecture.  You may want to peruse the directory for
	your architecture to see what packages are available.  The packages
	are also on the OpenBSD FTP mirror sites.  See

		http://www.openbsd.org/ftp.html

	for a list of current ftp mirror sites.

	Installation of a package is very easy.
	1) become the superuser (root)
	2) use the ``pkg_add'' command to install the software

	``pkg_add'' is smart enough to know how to download the software
	from the OpenBSD ftp server.  Example:

    $ su
    Password: <enter your root password>
    # pkg_add -v ftp://ftp.openbsd.org/pub/OpenBSD/2.7/packages/<arch>/emacs-20.3.tgz

	Packages available include:

		Go see
		pub/OpenBSD/2.7/packages/i386/
		pub/OpenBSD/2.7/packages/m68k/
		pub/OpenBSD/2.7/packages/alpha/

	Note: these packages may not exist for all architectures; other
	packages may be added.

Installing applications from the CD-ROM ports collection:

	The CD-ROM ``ports'' collection is a set of Makefiles, patches,
	and other files used to control the building and installation
	of an application from source files.  The source files come
	from archives which are also, for the most part, on the
	OpenBSD CD-ROM.

	Creating an application from sources can require a lot of
	disk space, sometimes 50 megabytes or more.  The first step is
	to determine which of your disks has enough room.  Once you've
	made this determination read the file README.ports on CD-ROM 2
	to see how to copy or mount the ports directory.

	To build an application you must:

	1) become the superuser (root)
	2) mount CD-ROM number 2 on the directory /cdrom.  This is
	   necessary to find the application source files.
	3) cd to the ports directory containing the port you wish
	   to build.  To build samba, for example, where you'd
	   previously copied the ports files into the /usr/ports
	   directory: cd /usr/ports/net/samba
	4) make FETCH_SYMLINK_DISTFILES=YES
	5) make FETCH_SYMLINK_DISTFILES=YES install
	6) make FETCH_SYMLINK_DISTFILES=YES clean

	The FETCH_SYMLINK_DISTFILES=YES parameter tells make not to copy
	the application's distribution sources from the cdrom to your hard
	disk, but instead create a symbolic link pointing to the CD-ROM.
	This is done to conserve disk space.

Installing applications from the OpenBSD ports collection:

	See http://www.openbsd.org/ports.html for current instructions
	on obtaining and installing OpenBSD ports.

Installing other applications:

	If an OpenBSD package or port does not exist for an application
	you're pretty much on your own.  The first thing to do is ask
	ports@openbsd.org if anyone is working on a port -- there may
	be one in progress.  If no luck there you may try the FreeBSD
	ports or NetBSD package collection.  If you are on an i386 based
	machine it is quite possible that the FreeBSD port, if one exists,
	will work for you.

	If you can't find an existing port try to make your own and
	feed it back to OpenBSD.  That's how our ports collection grows.
	Some details can be found at http://www.openbsd.org/porting.html
	with more help coming from the mailing list, ports@openbsd.org.
