上記のファイルリストを出力するため作成したシェルスクリプト
なお、SL-Zaurus の grep コマンド（busybox）のバグ（-v、--revert-match が使用できない）ため
一発で、工場出荷時に元々存在し、wlan-prism3_1.0.0-B_arm.ipk のインストール時に上書きされる
ファイルの一覧を出力することは断念した

【使い方】
wlan-prism3_1.0.0-B_arm.ipk インストールパッケージと同じディレクトリに下記のシェルスクリプト
（ここではファイル名を check.sh とした）を置き実行する

bash-2.05$ ls wlan-prism3_1.0.0-B_arm.ipk
wlan-prism3_1.0.0-B_arm.ipk
bash-2.05$ ./check.sh
