 ##Installing tuxpaint from distribution sources
 
+Distribution source packages usually include a "pristine" source archive of the original upstream source code, along with some metadata and/or patches for building corresponding distribution binary package(s).
+
+Run `apt source tuxpaint`.  Use `ls` to see what has been downloaded.  Also note that the downloaded files have been unpacked into a directory.  Use `cd` to change into that directory and have a look around.
+
+Use the editor of your choice to edit `Makefile` in this directory.  Append something to the value of `VER_VERSION` in this file.  For example:
+
+```
+VER_VERSION:=0.9.22-hacked
+```
+
+Now build binary packages by running `dpkg-buildpackage -n -nc`.
+
+Find the created packages and install them (using `dpkg -i`).  This will cause the packages you installed earlier to by replaced by the ones you just built.
+
+Now, run `tuxpaint` and note the version number on the splash screen.  Do you notice anything different?
+
+Uninstall the tuxpaint packages:
+
+```
+sudo dpkg -P $(dpkg -l | grep tuxpaint | awk '{print $2}')
+```
+
+:-)
