Welcome to GNU Common Lisp (GCL for short).
Here are some functions you should learn first.

	(HELP symbol) prints the online documentation associated with the

	about the CONS function, the CONS data type, and so on.

	(HELP* string) prints the online documentation associated with those
	symbols whose print-names have the string as substring.  For example,
	(HELP* \"PROG\") will print the documentation of the symbols such as
	PROG, PROGN, and MULTIPLE-VALUE-PROG1.

	(SI::INFO <some string>) chooses from a list of all references in the
        on-line documentation to <some string>.

	(APROPOS <some string>) or (APROPOS <some string> '<a package>) list
        all symbols containing <some string>.

	(DESCRIBE '<symbol>) or (HELP '<symbol>) describe particular symbols.
