In the branch of mathematics we use in ports, 5.03 > 5.1.  Because 5.03
and 5.3 are equivalent in it.  Each period-separated number is compared
from first to last number, until a version difference is encountered.
In this case:

Analog	Version 5.03	Version 5.1	Result
First	5		5		=
Second	3		1		>

Therefore, 5.03 > 5.1.

Or something.
