+# ------------------------------------------
+# 共有フォント圧縮時のロード速度実験
+#
+# 作成者 : nishikawa_takeshi
+# ------------------------------------------
+
+実験は以下の2ステップから構成されます。
+
+1. 共有フォントの圧縮とインポート
+2. ロード速度の測定
+
+以下、各ステップについて説明します。
+
+
+# ------------------------------------------
+# ステップ1  共有フォントの圧縮とインポート
+# ------------------------------------------
+
+(1)共有フォントの圧縮
+
+compSharedFont ディレクトリに移動して make してください。
+ % cd compSharedFont
+ % make
+
+(2)圧縮したフォントのインポート
+
+圧縮された共有フォントを NandInitializerRed でインポートする必要がありますが、
+NandInitializerRed は、SDからではなく、ROMアーカイブからインポートします。
+(つまり、自身のSRL内部に共有フォントを持ちます。)
+そのため、NandInitializerRed を再度、ビルドする必要があります。
+圧縮フォントは(1)の処理によって、NandInitializerRed のディレクトリに自動的にコピーされますので、
+コピーする必要はありません。
+
+ % cd $(TWL_IPL_RED_ROOT)/build/systemMenu_tools/NandIntializerRed
+ % make clean; make
+
+再ビルドされた NandInitializerRed.srl (ARM9.TWL/bin/以下にあります) をSDカードにコピーして、
+SDカードブートすると、メニューからフォントをインポートする項目を選択できます。
+
+# ------------------------------------------
+# ステップ2  ロード速度の測定
+# ------------------------------------------
+
+ロード速度の測定プログラムは、testLoadSpeed ディレクトリにあります。
+ここで、OS ライブラリの共有フォント関連の関数を変更し、
+されに、TWLSDK を SYSMENU パッケージとしてビルドしなおす必要があります。
+これらの変更とテストプログラムのビルドは、make にオプションをつけると自動的に実行されます。
+(お好みで、TWL_WITHOUT_DEMOS=TRUE や TWL_FINALROM=TRUE オプションをおつけください。)
+
+  % cd testLoadSpeed
+  % make TEST_TWLSDK_REBUILD=TRUE
+
+上記の TWLSDK の変更をしないときには、テストプログラムのビルドが正常にできません。
+
+テストプログラムを変更する場合、毎回 TWLSDK をビルドするのは時間がかかりますので、
+オプションをつけずに make すると、テストプログラムのビルドのみ実行します。
+
+  % make
+
+作成されたテストプログラムを実行すれば、圧縮した共有フォントのロード時間を測定できます。
