+# This is a reference script to add checksums to downloadable               #
+# subscriptions. The checksum will be validated by AutoProxy on download    #
+# and checksum mismatches (broken downloads) will be rejected.              #
+#                                                                           #
+# To add a checksum to a subscription file, run the script like this:       #
+#                                                                           #
+#   perl addChecksum.pl subscription.txt                                    #

+# Note: your subscription file should be saved in UTF-8 encoding, otherwise #
+# the generated checksum might be incorrect.                                #
+#                                                                           #

sendGFWList.sh

+#!/bin/bash
+#
+# 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 repository 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 gfwlist.txt > list.txt
+#     $git add list.txt
+#     $git commit -a -m "init"
+#   Normal Usage:
+#     edit list.txt as usual;
+#     $./synGfwList.sh "say something about this edit"
+# Note:
+#   1: You can use "git" to show, diff, log...what's you want;
+#   2: "gfwlist.txt" is a fake file, do NOT commit "list.txt" to svn server;
+#   3: Do NOT use any unicode character in the list, there is a known bug.
