Hi,

I am going to export data to excel file from my project.  
I am using spreadsheet-excel (0.3.5.1) gem to read/write data in excel.  
I got #\<MaxSizeError: MaxSizeError\> error when exporting some amount of  
data to excel.  
when i am searching for the above problem , i got  
spreadsheet-excel-ole-storage.patch and parseexcel-ole-storage.patch as  
a solution from [GitHub - aquasync/ruby-ole: A library for easy read/write access to OLE compound documents for Ruby](http://code.google.com/p/ruby-ole/wiki/ExcelPatches).  
(i got the patches from  
[GitHub - aquasync/ruby-ole: A library for easy read/write access to OLE compound documents for Ruby](http://code.google.com/p/ruby-ole/source/browse/trunk/contrib/?r=51)).

Now i just want to know how to use these patch ???
