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
