[FreeBSD] 取得 FreeBSD CVSUP 的更新狀態

在 Sayya Joehorn 個人版看到有人實做出偵測台灣 CVSUP Server 更新狀態，以及更新的時間，也有程式碼的釋出，參考這篇：Script: 取得 FreeBSD CVSUP 的更新狀態，這篇寫的蠻清楚的，只需要 perl 跟 php 就可以完成，不過在使用過程有些事項必須要注意，在 FreeBSD 6.2 R 之後，已經內建了 csup 指令來更新 ports 或者是核心，所以要在另外安裝上 cvsup ports 套件，在 Perl 方面，也先裝 net/p5-Net-Rendezvous 才可以正確使用。

# 安裝必備軟體
cd /usr/ports/net/p5-Net-Rendezvous/ && make install clean
cd /usr/ports/net/cvsup-without-gui && make install clean

Perl 程式碼我有改過一些，不然沒辦法抓到正確資訊：

PHP 顯示部份，這邊就沒有動到，直接 copy 就可以
