池田です。
Feedmap作成ソフトウェアを作成したので公開します。

feedmap   - Make NetNews Feed map from news spool.

1. はじめに
feedmapはNetNewsのフィードの状態を図に表示するためのスクリプトです。
よく知られたプログラムとしてmakefeedmapがありますが、必要とするプログラムのひとつ
collect-swが入手できないので代替手段として作成いたしました。

2. makefeedmapとの違い
長所:
・運用中のニュースサーバであれば今すぐにでもフィードマップを作成可能
・作成期間を任意に混在可能
短所
・データを毎回収集するので低速
・転送量にかかわらず接続線の太さは一定

3. 必要なソフトウェア
UNIXで標準的に入ってると思われるソフトウェアの他に、graphvizの中のdotという
プログラムが必要です。
詳細はスクリプトの先頭部を参照してください。

4. 簡単な使いかた
コマンドのフルパス、ファイル関係のパス、作図期間を指定したらそのまま実行すれば
作図されます。
基本的には、cronから呼び出される形で使うことを前提にしています。

5. その他
出力のサンプルを

においてあります。
その他、質問等は
