Good news for all MetaPost fans!
Therion 0.2.17 supports
* easy switching among predefined map symbol sets
(symbol-set, symbol-assign, symbol-hide options of the
layout command)
* customized map symbols loaded in the run-time
(new symbols may be defined inside of 'code metapost' section
of the layout command)
There is no need to recompile Therion when new symbols are added.
* optical map scaling (base-scale option)
