Cross-assembler for 65xx/R65C02/65816

 -v           verbose output
 -x           old filename behaviour (overrides `-o', `-e', `-l')
              This is deprecated and may disappear in future versions!
 -C           no CMOS-opcodes
 -W           no 65816-opcodes (default)
 -w           allow 65816-opcodes
 -B           show lines with block open/close
 -c           produce `o65' object instead of executable files (i.e. don't link)
 -o filename  sets output filename, default is `a.o65'
                A filename of `-' sets stdout as output file
 -e filename  sets errorlog filename, default is none
 -l filename  sets labellist filename, default is none
 -r           adds crossreference list to labellist (if `-l' given)
 -M           allow ``:'' to appear in comments for MASM compatibility
 -R           start assembler in relocating mode
 -Llabel      defines `label' as absolute, undefined label even when linking
 -b? addr     set segment base address to integer value addr
                `?' stands for t(ext), d(ata), b(ss) and z(ero) segment
                (address can be given more than once, last one is used)
 -A addr      make text segment start at an address that when the _file_
                starts at addr, relocation is not necessary. Overrides -bt
                Other segments must be specified with `-b?'
 -G           suppress list of exported globals
 -DDEF=TEXT   defines a preprocessor replacement
 -Ocharset    set output charset (PETSCII or ASCII), case-sensitive
 -Idir        add directory `dir' to include path (before XAINPUT)
  --version   output version information and exit
  --help      display this help and exit
