Reference Implementation

This implementation IS FULLY 30W-compliant.

A reference perl implementation is available: view download

It cannot automatically apply the 30W rule, as it doesn't take your location into consideration. If you're East of 30W, call it with the -e option and it will yield the correct results.

Any problems or issues should be mentioned to Zigdon either on the wiki or in the Geohashing IRC channel, as well as posted at Talk:Implementations.
