First of all：欢迎任何针对该脚本的建议和批评。
起因：
看到论坛里有一些朋友在问从哪里下载 OpenBSD 的 ISO，但是 OpenBSD 官方并不提供 ISO
文件下载，因为 OpenBSD 的光盘销售是支持 OpenBSD 开发的一种经济来源，所以 OpenBSD
官方希望支持 OpenBSD 的朋友和用户都能购买它的光盘以支持 OpenBSD 的持续发展。
***************************************************
我们强烈建议您：如果可能的话，请购买 OpenBSD 官方制作的 CD 套装。
详情请访问：
http://www.openbsd.org/faq/faq3.html#BuyCD
***************************************************
脚本的使用方法：
$ ./mk_openbsd_iso-0.1.sh 3.9 i386
您只要指定需要制作的 OpenBSD 版本和平台架构，即可生成对应的 ISO 文件。
此脚本需要 wget / mkisofs 这两个工具才能制作ISO。
wget 用于下载文件，mkisofs 用于制作 ISO。
cd /usr/ports/sysutils/cdrtools
make install clean;
cd /usr/ports/ftp/wget
make install clean;
注意事项：
并不是每个平台都可以使用 CD 启动安装，详情请访问：
http://www.openbsd.org/faq/faq4.html#Overview
默认创建的 ISO 文件不会带有任何的 packages，如果你需要将 packages 包含进去，
请阅读脚本中函数 FETCH_PKGS() 的说明。
以下是完整的脚本：

# Author : MichaelBibby <

# Date : 2006.07.24
# Purpose : Automatic download file sets and create an OpenBSD -release or
# -snapshots ISO.
# Version : 0.2.1
# Usage : ./mk_openbsd_iso.sh [3.9|4.0|snapshots] [i386|amd64|sparc64]
# ChangeLog:
# * 0.2 --> 0.2.1:
# - Fix the bug when get value of CDROM_FS.
# * 0.1 --> 0.2:
# - Add function FETCH_SRC to fetch source code and ports tarballs.
# - Modify some temp directories and little adjustment.
VERSION="$1" # Special OpenBSD version, like 3.9, 4.0, snapshots.
ARCH="$2" # Maechine architecture, like i386, amd64.
TMP_ARCHIVE="$HOME/tmp/openbsd/$VERSION" # Store all openbsd file sets.
SRC_ARCHIVE="$TMP_ARCHIVE/$VERSION" # Store source code and ports tarball.
SETS_ARCHIVE="$TMP_ARCHIVE/$VERSION/$ARCH" # Store all installation file sets.
PKGS_ARCHIVE="$TMP_ARCHIVE/$VERSION/$ARCH/packages" # Store all packages.
