Procedure 1.1.  GNU hello test build

1. Fetch the software

   wget http://gnu.xl-mirror.nl/hello/hello-2.7.tar.gz
tar zxf hello-2.7.tar.gz

2. Create ./debian and contents

   cd hello-2.7/
echo|dh_make -f ../hello-2.7.tar.gz -s -c gpl3 && rm debian/{*.ex,*.EX,README.*}

3. Build

   DIST=sid pdebuild

   That should generate a lot of output, ask you for your GPG password, and then leave a package in the parent directory. You can use debc to see the contents, or lintian to see that it contains errors.
