+
+ 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.
