This directory contains a Mapcode encoding/decoding utility. To build the original Mapcode tool, execute:

gcc -O mapcode.cpp -o mapcode

(Or if you need to make sure there are no warnings:)

gcc -Wall -Wstrict-prototypes -Wshorten-64-to-32 -O mapcode.cpp -o mapcode

For help, simply execute:

./mapcode

As an example, type:

./mapcode --decode NLD XX.XX

This tool provides a rather extensive command-line interface to encode and decode Mapcodes.
