.SH NAME

acpihelp \- ACPI help utility

.SH SYNOPSIS

.B acpihelp

.RI <option> ...

.RI [<name-prefix>|<hex-value>]

.SH DESCRIPTION

This manual page briefly documents the

.B acpihelp

command. The option list is taken from the acpihelp interactive help.

.PP

.\" TeX users may be more comfortable with the \fB<whatever>\fP and

.\" \fI<whatever>\fP escape sequences to invode bold face and italics, 

.\" respectively.

.B acpihelp

provides descriptive text for AML and ASL keywords, methods, and opcodes.

.PP

Much more detailed documentation may be found at

http://www.acpica.org/documentation/.

.PP

If neither a <name-prefix> or a <hex-value> is provided,

.B acpihelp

will do the logical equivalent of a "display all."

.PP

A default search (that is, a search with no options) and a <name-prefix>

can mean two different things: (1) if <name-prefix> does not start with

an underscore, find ASL operator names, or (2) if <name-prefix> does start

with an underscore, find ASL predefined method names.
