+#The Nerv IO Package#
+Part of the [Nerv](../README.md) toolkit.

+##Description##
+There are four classes in to deal with chunk data, which are __nerv.ChunkFile__, __nerv.ChunkFileHandle__, __nerv.ChunkInfo__, __nerv.ChunkData__. Below is the underlying C structs.
+```
+typedef struct ChunkFileHandle {
+ FILE *fp;
+} ChunkFileHandle;
+
+typedef struct ChunkInfo {
+ off_t offset, length;
+} ChunkInfo;
+
+typedef struct ChunkData {
+ FILE *fp;
+ char *data;
+} ChunkData;
+```
+
+##Methods##
+* __ChunkFileHandle ChunkFile.\_\_init(string mode, string fn)__
+`mode` can be `r` or `w`, for reading or writing a file.

+Copy a part of `mb`(rows of index `[b_begin..b_end)`) to `ma` beginning at row index `a_begin`. If not specified, `b_begin` will be `0`, `b_end` will be `b.nrow`, `a_begin` will be `0`.
##Examples##
* Use `get_dataref_value` to test __Nerv__'s matrix space allocation.

+#The Nerv Parameter Package#
+Part of the [Nerv](../README.md) toolkit.
+
+##Description##
+###Class hierarchy###
+There is a base class __Nerv.Param__ defined in `layer/init.lua`.
+__Nerv.MatrixParam__ inherits __Nerv.Param__.
+__Nerv.LinearTransParam__, __Nerv.BiasParam__ inherits __Nerv.MatrixParam__.
+###Class member###
+* __Nerv.MatrixParam__
+ * __nerv.CuMatrix__ trans
+ Stores the parameter matrix.
+
+##Methods##
+* __void Param.\_\_init(Param self, string id, table global_conf)__
+Constructor of a __Param__, it will set `self.id` to be `id` and `self.gconf` to be `global_conf`.
+* __void Param.set_info(table info)__
+Set `self.info` to be `info`.
+* __table Param.get_info()__
+Returns `self.info`.
+* __void Param.read(ChunkData pcdata)__
+This is not implemented in `nerv.Param`.
+* __void MatrixParam.read(MatrixParam self, ChunkData pcdata)__
+Read `self.trans` from `pcdata`.
+* __void MatrixParam.write(MatrixParam self, ChunkFileHandle pfhandle)__
+Write `self.trans` to `pfhandle`. \ No newline at end of file
