Hey Rajesh:
I do not know it is a common pattern or not. The following was the contents at the top in my README.txt file.
Contents:
---------
*THE VERSION OF
JAVA(TM) 2 SDK, STANDARD EDITION, AND PLATFORM USED
*INSTRUCTIONS ON HOW TO EXECUTE THE PROGRAM
*THE LOCATION OF DATABASE FILE
*THE LOCACTION OF DESIGN CHOICES DOCUMENT
*A LIST OF FILES SUBMITTED HEREWITH
Then I described above them as a subtitle, what are they? how to execute? and where are they? That is all.
Good luck. -Bal
