Phyton script for looking files with specific text pattern, in a directory tree.
'''
Hi, This is the minimized version of some more
complicated script I wrote for some project.
What we basically do here is look for some files (with the same name)
with specific text pattern in it. All files with this
"magic" pattern will be opened with notepad.
