      (description
       "This package provides a compiler and assembler that target the Piet
graphical programming language.

@command{piet-assembler} converts Piet assembler instructions (e.g.,
@code{push}, @code{add}, @code{switch}, @code{outn}) and directives into an
executable @code{netpbm} image of the corresponding Piet program.

@command{piet-compiler} compiles a C-like high-level language into assembly
source understood by @command{piet-assembler}.  It supports common arithmetic
and boolean logic operators (though not bitwise manipulation), flow control
(@code{if}, @code{for}, @code{while}), recursive functions, in-line assembler,
and input/output intrinsics.  The only supported data type is the integer.

The language is documented only by the compiler's Perl source code and the
included samples.")
