+description         Historical computer simulator forked from SIMH
+
+long_description    ZIMH, which stands for \"ZIMH Implements Machine History\", \
+                    is a software emulator for historically important \
+                    computer systems and peripherals. It is a hard fork of \
+                    SIMH with a substantially different development track.
