DESCRIPTION="webcam view tools use sdl lib." # 这是对你的软件包进行的简短说明
HOMEPAGE="http://mxhaard.free.fr" # 这个就没什么好说的了,如果你在某个站点发布你的软件,那在这里加上网站的链接就是了
#MY_PV=20060127
SRC_URI="http://mxhaard.free.fr/spca50x/Download/${PN}${PV}.tar.gz"
SLOT="0" # 通常这里写成0就可以了,这主要用于GCC,emacs这类可以多版本共存的软件包
#IUSE="linguas_zh_CN ssl applet systray doc" # 这里设置USE标记,较为复杂,这里就只加一个doc作例子了
IUSE=""
LICENSE="GPL-2" # 我们痛恨但又不可避免的软件许可
KEYWORDS="x86 amd64" #这只是个简单的脚本,所以在各种架构上都应该是可以正常运行的,不过,我们只想在x86上测试它
#并且所有起始的ebuild都应该先进行测试，所以只写上~x86

src_unpack() # 这个函数用于解压源代码
{
#当前ebuild可以不用声明此函数 但为了学习而显示一些变量而用的
# ${S}是src_unpack函数起始执行的地方，由emerge系统自动创建
#cp ${FILESDIR}/unmask.gz ${S}
#FILESDIR这个变量指明了我们存放该包的路径也就是
#/usr/portage/local/myebuilds/app-portage/unmask/files
#gzip -d ${S}/unmask.gz

#------------------ 一个使用第三方ebuild的示例---------------------------
#sudo mkdir /usr/local/myportage/net-misc/g2ipmsg/files -p
#cd /usr/local/myportage/net-misc/g2ipmsg/files
#--------------------
#add PORTDIR_OVERLAY to /etc/make.conf
#PORTDIR_OVERLAY="/usr/local/myportage"
#PORTDIR_OVERLAY="${PORTDIR_OVERLAY} /usr/portage/local/layman/gentoo-china"
#sudo sh -c "echo net-misc/g2ipmsg >> /etc/portage/package.keywords"
#sudo sh -c 'echo "net-misc/g2ipmsg ssl applet doc systray >> /etc/portage/package.use'
#不用这一步
#sudo ebuild ./g2ipmsg-0.9.5.ebuild digest
#sudo sh -c "USE=doc emerge g2ipmsg"
#cat /var/lib/portage/world | grep g2ipmsg
