embedded exe file into rtf file

[rawatds]

Hi All
I want a method in shell script which will embed the exe file into rtf file si that the rtf file can be open in word and so my exe.

Actually what is happening in my system at present :
The report in my system is a self-extracting Zip file with filetype '.EXE'. Double clicking on the attachment opens and decrypts the report.
But in some customers the attachement with '.exe' is being rejected due to virus protection mechanisms.

Now i am trying to write a mechanism in unix which will embed this exe file in some '.TXT' file so that it will not be rejected and can pass tru

Thanks in advance
Rawat
