If you have got the source package, see doc/compile.txt for instructions how to compile the stuff for the different systems. If you have a binary package: Have a look in the doc directory for information on how to use the tools. If the doc dir is mostly empty, you will have to install the (separate) documentation package. If you are new to cc65, the file intro.txt may be of interest to you. To avoid having to mess with paths, you may want to set the environment variables CC65_LIB and CC65_INC to the directory containing the libraries and the system include files respectively. If you have installed cc65 in C:\cc65 (assuming a DOS or Windows system), you should use set CC65_LIB=c:\cc65\lib and set CC65_INC=c:\cc65\include Unix people probably know, how to translate these lines into the appropriate Unix commands:-) Have fun!
