+.Sh DESCRIPTION
+The
+.Nm
+utility is a compiler/decompiler for ACPI Source Language (ASL)
+and ACPI Machine Language (AML).  Major features of
+.Nm
+include:
+.Pp
+.Bl -bullet -compact -offset indent
+.It
+Full support for the ACPI 2.0b Specification including ASL grammar
+elements and operators.
+.It
+Extensive compiler syntax and semantic error checking, especially in
+the area of control methods. This reduces the number of errors that are
+not discovered until the AML code is actually interpreted (i.e., the
+compile-time error checking reduces the number of run-time errors.)
+.It
+Multiple types of output files, including formatted listing files with
+intermixed source, several types of AML files, and error messages.
+.El
+.Sh OPTIONS
+.Bl -tag -width indent
+.It Fl b Ar p|t|b
+Create compiler debug/trace file (*.txt). Types: Parse/Tree/Both
+.It Fl c
+Parse only, no output generation
+.It Fl d Ar file
+Disassemble AML to ASL source code file (*.dsl)
+.It Fl dc Ar file
+Disassemble AML and immediately compile it
+(Obtain DSDT from current system if no input file)
+.It Fl e
+Generate External() statements for unresolved symbols
+.It Fl f
+Ignore errors, force creation of AML output file(s)
+.It Fl g
+Get ACPI tables and write to files (*.dat)
+.It Fl h
+Additional help and compiler debug options
+.It Fl hc
+Display operators allowed in constant expressions
+.It Fl hr
+Display ACPI reserved method names
+.It Fl i Ar a|c
+Create assembler or C include file (*.inc or *.h)
+.It Fl l
+Create mixed listing file (ASL source and AML) (*.lst)
+.It Fl ln
+Create namespace file (*.nsp)
+.It Fl ls
+Create combined source file (expanded includes) (*.src)
+.It Fl oa
+Disable all optimizations (compatibility mode)
+.It Fl of
+Disable constant folding
+.It Fl oi
+Disable integer optimization to Zero/One/Ones
+.It Fl on
+Disable named reference string optimization
+.It Fl ot
+Display compile times
+.It Fl p Ar prefix
+Specify filename prefix for all output files (including .aml)
+.It Fl s Ar a|c
+Create AML in assembler or C source file (*.asm or *.c)
+.It Fl t Ar a|c
+Create AML in assembler or C hex table (*.hex)
+.It Fl vi
+Less verbose errors and warnings for use with IDEs
+.It Fl vo
+Enable optimization comments
+.It Fl vr
+Disable remarks
+.It Fl vs
+Disable signon
+.It Fl x Ar level
+Set debug level for trace output
