Flash收藏站
我的个人Flash收藏站首页装修完毕！顺带用C++写了俩RSS、站点地图生成器
首页图片：
页脚：
这是我搜刮的Flash游戏收藏站，今天装修了页面颜色和页脚，新颜色看着舒服多了
RSS订阅文件生成器：
此RSS订阅生成器是通过读取我预留的Json元信息生成的，新链接的时间为第一次运行时间，链接的时间会储存在日志中，xml的优先级大于日志，可以手动修改xml RSS订阅时间，手动修改xml中的时间会在下一次程序运行时被更新进日志。
Json格式为：
[
{
"name": "驾驶TU-95",
"desc": "驾驶战略轰炸机TU-95！带有汉化"
},
{
"name": "文具防御",
"desc": "使用文具打击来犯之敌！带有汉化"
}
