Moving lines within a txt file

A newbie to shell scripting.....

I need some assistance in doing the following:

I have a system generated text file(a makefile basically).

Before I can execute the make command, I need to modify one section of this generated file.

The generated section is as follows:

# INCLUDE macro for SCI
#~~~~~~~~~~~~~~~~~~~~~~~
XYZ_MAIN_INCLUDE = \
-I/Path_1 \
-I/Path_2 \
-I/Path_3 \
-I/Path_4

Basically, Path_4 has be placed at the start of the INCLUDE section with appropriate changes to new line delimiters.

This modified section should look as follows:

# INCLUDE macro for SCI
#~~~~~~~~~~~~~~~~~~~~~~~
XYZ_MAIN_INCLUDE = \
-I/Path_4 \
-I/Path_1 \
-I/Path_2 \
-I/Path_3

I have to make similar changes to 6 different files in 6 different locations in the directory structure before I can execute make.

Can I achieve this using a shell script without having to modify all the files manually everytime I need to execute a make?

Thanks in advance for any suggestions.

MAKESH(1)						      General Commands Manual							 MAKESH(1)

NAME
makeSH - a .SH script maker SYNOPSIS
makeSH files DESCRIPTION
MakeSH examines one or more scripts and produces a .SH file that, when run under sh, will produce the original script. The .SH script so produced has two sections containing code destined for the output. The first section has variable substitutions performed on it (taking values from config.sh), while the second section does not. MakeSH does not know which variables you want to have substituted, so it puts the whole script into the second section. It's up to you to insert any variable substitutions in the first section for any values you want from config.sh. You should run makeSH from within your top-level directory and use the relative path to the file as an argument, so that the "Extracting ..." line printed while running the produced .SH file later on will give that same path.

It could assume that variables from metaconfig's Glossary need to be initialized in the first section, but I'm too lazy to make it do that. LOCAL MAKESH(1)
