+
+MIX programs, as executed by @code{mixvm}, are composed of binary
+instructions loaded into the virtual machine memory as MIX
+words. Although you could write your MIX programs directly as a series
+of words in binary format, you have at your disposal a more friendly
+assembly language, MIXAL (@pxref{MIXAL}) which is compiled into binary
+form by @code{mixasm}, the MIXAL assembler included in @sc{mdk}. In this
+chapter, you will find a complete description of @code{mixasm} options.

+@section Invoking @code{mixasm}
+
+In its simplest form, @code{mixasm} is invoked with a single argument,
+which is the name of the MIXAL file to be compiled, e.g.
+
+@example
+mixasm hello
+@end example
+
+@noindent
+will compile either @file{hello} or @file{hello.mixal}, producing a
+binary file named @file{hello.mix} if no errors are found.
+
+In addition, @code{mixasm} can be invoked with the following command
+line options (note, that, following GNU's conventions, we provide a long
+option name for each available single letter switch):
+
+@example
+mixasm [-vhulg] [-o OUTPUT_FILE] [--version] [--help]
+       [--usage] [--debug] [--output=OUTPUT_FILE] [--list[=LIST_FILE]] file
+@end example
+
+@noindent
+The meaning of these options is as follows:
+
+@defopt -v
+@defoptx --version
+Prints version and copyleft information and exits.
+@end defopt
+
+@defopt -h
+@defoptx --help
+@defoptx -u
+@defoptx --usage
+Prints a summary of available options and exits.
+@end defopt
+
+@defopt -g
+@defoptx --debug
+Includes debugging information in the compiled file, allowing breakpoint
+setting at source level and symbol table inspection under @code{mixvm}.
+@end defopt
+
+@defopt -o output_file
+@defoptx --output=output_file
+By default, the given source file @var{file.mixal} is compiled into
+@var{file.mix}. You can provide a different name for the output file
+using this option.
+@end defopt
+
+@defopt -l
+@defoptx --list[=list_file]
+This option causes @code{mixasm} to produce, in addion to the
+@file{.mix} file, an ASCII file containing a summary of the compilation
+results. The file is named after the MIXAL source file, changing its
+extension to @file{.mls} if no argument is provided; otherwise, the
+listing file is named according to the argument.
+@end defopt
