It looks like this,
Automatic indentation is supported by a full language parser. If
psl-program-name is set up then the current buffer can be executed
by the interpreter with

Automatic indentation benefits greatly from byte-compilation so it's a
good idea to byte-compile the package using the provided
Makefile. This will also generate an autoloads file, which would be
required instead of
Also included with psl-mode is a ParselTongue compiler which compiles
a ParselTongue program into Elisp. To compile and evaluate a
ParselTongue program inside of Emacs (no spawning other processes),

standalone with the provided
Compiled ParselTongue is about four orders of magnitude faster than the reference implementation interpreter. It can also parse much closer to the spec, giving more freedom to the programmer. However, there are a handful of semantic issues and one or two parser issues that remain in the compiler.
