'''Trace sources'''
|| This program uses the '''CongestionWindow''' trace source.
It tracks the changes in the congestion window size.

Now we will go through the steps required to use the '''TutorialApp''' class in our program.
|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"

|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
|| <span style="background-color:#ffffff;">Type </span><span style="background-color:#ffffff;">'''cp examples/tutorial/tutorial-app.cc src/applications/model'''</span>

|| Now we will copy the required files.

These folders and files are created by default when '''ns-3 '''is installed.

First we copy the file '''tutorial-app.cc'''.

Let us copy the file '''tutorial-app.cc '''which is available under <span style="background-color:#ffffff;">'''examples/tutorial folder.'''</span>

|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
|| Only narration
|| The destination is the '''model''' directory under the '''src/applications '''directory.

The '''src '''directory stores the header files and the associated source files.

These files can be imported in our program.
|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
|| <span style="background-color:#ffffff;">Type </span><span style="background-color:#ffffff;">'''cp examples/tutorial/tutorial-app.h src/applications/model'''</span>

|| Now we copy the file '''tutorial-app.h'''.

It is a header file.

It contains the required definitions for the '''TutorialApp '''class.
|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
|| Only narration
|| Once the files are copied, we need to edit the '''CMakeLists.txt''' file.

The '''CMakeLists.txt''' file lists the files that will be compiled during the build process.

We need to add the files we copied to the '''CMakeLists.txt '''file.
|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
|| <span style="background-color:#ffffff;">Type</span><span style="background-color:#ffffff;">''' gedit src/applications/CMakeLists.txt'''</span>

|| Using your favorite text editor, edit the '''CMakeLists.txt '''file.

It is present under the '''applications '''directory, which is under the '''src '''directory.

We are using the '''gedit '''text editor.
|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
|| <span style="background-color:#ffffff;">Under the SOURCE_FILES header, add the line: </span><span style="background-color:#ffffff;">'''model/tutorial-app.cc '''</span><span style="background-color:#ffffff;">after the last entry (usually model/udp-trace-client.cc)</span>

|| In the text editor, find the '''SOURCE_FILES '''header.

After the last line under the header, add the line '''model/tutorial-app.cc.'''
|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
|| <span style="background-color:#ffffff;">Under the HEADER_FILES header, add the line: </span><span style="background-color:#ffffff;">'''model/tutorial-app.h'''</span><span style="background-color:#ffffff;"> after the last entry (usually model/tutorial-app.h)</span>

|| Now find the '''HEADER_FILES '''header.

After the last line under the header, add the line <span style="background-color:#ffffff;">'''model/tutorial-app.h'''</span><span style="background-color:#ffffff;">.</span>

|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"

|| In the terminal, type .'''/ns3 configure.'''

This command scans for any changes in the build files.

|- style="border:1pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.206cm;padding-right:0.191cm;"
|| <span style="background-color:#ffffff;">Type </span><span style="background-color:#ffffff;">'''./ns3'''</span><span style="background-color:#ffffff;"> </span><span style="background-color:#ffffff;">'''build'''</span>
|| <span style="background-color:#ffffff;">Now type </span><span style="background-color:#ffffff;">'''./ns3 build '''</span><span style="background-color:#ffffff;">to start the build process.</span>

<span style="background-color:#ffffff;">This command scans the </span><span style="background-color:#ffffff;">'''CMakeLists.txt '''</span><span style="background-color:#ffffff;">file for new changes and builds the </span><span style="background-color:#ffffff;">'''ns-3 '''</span><span style="background-color:#ffffff;">program again.</span>

Pause the video here and wait for the build process to finish.

It could take several minutes.

<span style="background-color:#ffffff;">Now the </span><span style="background-color:#ffffff;">'''tutorial-app.h '''</span><span style="background-color:#ffffff;">header file is ready to be used in our program.</span>
