Simply review the Makefile and run `make`. 68 1.1 abs 69 1.1 abs Alternatively, 70 1.1 abs * `make clean` will delete all artifacts. 71 1.1 abs * `make lint` will format the code to standards. 72 1.1 abs * `make dist` will prepare a lha archive with the binaries. 73 1.1 abs 74 1.1 abs Development is done using the `bebbo/amiga-gcc` crossdev toolchain. 75 1.1 abs https://github.com/bebbo/amiga-gcc 76 1.1 abs 77 1.1 abs With some care so that building with `vbcc` is also supported. 78 1.1 abs http://sun.hasenbraten.de/vbcc/ 79 1.1 abs 80 1.1 abs ## Authors 81 1.1 abs * Roc Valls Domnech (2022) 82 1.1 abs * Christian E.
