# -> There are three files in each folder namely,
# 1).net
# 2).net.out
# 3).out

# ->Go to file .out
# search for text starting with .tran
# If found copy that entire statement

# else
# search for text starting with .ac
# If found copy that entire statement

# else
# do nothing


# ->Now go to .net.out
# search for text .control
# Paste statement copied in previous step in after .control in this file
# (i.e)between .control and run.
