+
+   Version Test - Simple program to run through a file and comare versions.
+   
+   Each version is compared and the result is checked against an expected
+   result in the file. The format of the file is
+       a b Res
+   Where Res is -1, 1, 0. dpkg -D=1 --compare-versions a "<" b can be
+   used to determine what Res should be. # at the start of the line
+   is a comment and blank lines are skipped
+
+   The runner will also call dpkg --compare-versions to check if APT and
+   dpkg have (still) the same idea.
