+%description
+z80dasm is a disassembler for the Zilog Z80 microprocessor and
+compatibles. It can be used to reverse engineer programs and operating
+systems for 1980's microcomputers using this processor architecture
+(for example ZX81, Spectrum, Galaksija and many others).  Generated
+assembly code can be assembled back with a number of Z80
+assemblers. Compatibility with z80asm was thoroughly tested.
