 # $FreeBSD$
 #
 # Makefile for building releases and release media.
 #
 # User-driven targets:
 #  cdrom: Builds release CD-ROM media (disc1.iso)
 #  dvdrom: Builds release DVD-ROM media (dvd1.iso)
 #  memstick: Builds memory stick image (memstick.img)
 #  mini-memstick: Builds minimal memory stick image (mini-memstick.img)
 #  ftp: Sets up FTP distribution area (ftp)
 #  release: Invokes real-release, vm-release, and cloudware-release targets
 #  real-release: Build all media and FTP distribution area
 #  vm-release: Build all virtual machine image targets
 #  cloudware-release: Build all cloud hosting provider targets
 #  install: Invokes the release-install and vm-install targets
 #  release-install: Copies all release installation media into ${DESTDIR}
 #  vm-install: Copies all virtual machine images into ${DESTDIR}
 #
 # Variables affecting the build process:
 #  WORLDDIR: location of src tree -- must have built world and default kernel
 #            (by default, the directory above this one)
 #  PORTSDIR: location of ports tree to distribute (default: /usr/ports)
 #  DOCDIR:   location of doc tree (default: /usr/doc)
 #  XTRADIR:  xtra-bits-dir argument for <arch>/mkisoimages.sh
 #  NOPKG:    if set, do not distribute third-party packages
 #  NOPORTS:  if set, do not distribute ports tree
 #  NOSRC:    if set, do not distribute source tree
 #  NODOC:    if set, do not generate release documentation
 #  WITH_DVD: if set, generate dvd1.iso
 #  WITH_COMPRESSED_IMAGES: if set, compress installation images with xz(1)
 #		(uncompressed images are not removed)
 #  WITH_VMIMAGES: if set, build virtual machine images with the release
 #  WITH_COMPRESSED_VMIMAGES: if set, compress virtual machine disk images
 #  		with xz(1) (extremely time consuming)
 #  WITH_CLOUDWARE: if set, build cloud hosting disk images with the release
 #  TARGET/TARGET_ARCH: architecture of built release
 #
