# A simple script help to maintain AutoProxy gfwList easily.
#
# Function:
# Update local svn repository;
# Commit decoded changes(by others in your team) to local git repository
# with decoded message and authors name;
# Update "Last Modified" time;
# Update "Checksum";
# Commit your changes to local git repository;
# Commit your encoded changes to remote svn server with encoded log.
# Usage:
# Initialize:
# $svn checkout https://autoproxy-gfwlist.googlecode.com/svn/trunk/ gfwList --username your-google-user-name
# $cd gfwList
# $git init
# $base64 -d gfwlist.txt > list.txt
# $git add list.txt
# $git commit -a -m "init"
# Normal Usage:
# edit list.txt as usual;
# $./sendGFWList.sh "say something about this edit"
# Note:
# 1: You can use "git" to show, diff, log...what's you want;
# 2: Do NOT commit "list.txt" to svn server (it won't by default);
# 3: Do NOT use any unicode character in the list, there is a known bug;
# 4: Do NOT "svn update", run this script to update / commit at any time.
