- * メモリマネージャ
- * malloc , free の処理を効率的に出来るようにしたもの。
- * 複雑な処理を行っているので、若干重くなるかもしれません。
- *
- * データ構造など（説明下手ですいません^^; ）
- * ・メモリを複数の「ブロック」に分けて、さらにブロックを複数の「ユニット」
- * に分けています。ユニットのサイズは、１ブロックの容量を複数個に均等配分
- * したものです。たとえば、１ユニット32KBの場合、ブロック１つは32Byteのユ
- * ニットが、1024個集まって出来ていたり、64Byteのユニットが 512個集まって
- * 出来ていたりします。（padding,unit_head を除く）
- *
- * ・ブロック同士はリンクリスト(block_prev,block_next) でつながり、同じサイ
- * ズを持つブロック同士もリンクリスト(hash_prev,hash_nect) でつな
- * がっています。それにより、不要となったメモリの再利用が効率的に行えます。

+* Memory manager
+* able to handle malloc and free efficiently
+* Since the complex processing, I might be slightly heavier.
+*
+* (I'm sorry for the poor description ^ ^;) such as data structures
+* Divided into "blocks" of a plurality of memory, "unit" of a plurality of blocks further
+* I have to divide. Size of the unit, a plurality of distribution equal to the capacity of one block
+* That's what you have. For example, if one unit of 32KB, one block 1 Yu 32Byte
+* Knit, or are able to gather 1024, gathered 512 units 64Byte
+* I can be or have. (Excluding padding, the unit_head)
+*
+* Lead-linked list (block_prev, block_next) in each other is the same size block
+* Linked list (hash_prev, hash_nect) even among such one in the block with the figure
+* I like to have. Thus, reuse of memory no longer needed can be performed efficiently.
