NOTE!!!
As of May 2025 the purchase of a Lertap5 license became unnecessary. Lertap5 is now free. No license is required.
(A license used to go for $78 and, until a license was purchased, Lertap5 would be limited to processing just 250 data records -- users could have more than 250, but in such cases, Lertap5 would stop reading records once 250 of them had been processed.))
