+dis6502 (flow-tracing disassembler for 6502)
+
+dis6502 is a 6502 disassembler that supports Atari 8-bit and Commodore
+executables, as well as raw memory dumps. It attempts to separate code
+sections from data by tracing the flow of execution, and supports a config
+file for manually defining code sections that aren't reached by the trace.
+
+Note: This is NOT the dis6502 from AtariMax. Although the name is the
+same, AtariMax's disassembler is completely different (for one thing,
+it's a Windows GUI application).

+.SH SYNOPSIS
+.sp
+dis6502 [\fI\-b\fP | \fI\-l\fP | \fI\-c\fP | \fI\-r <address>\fP] [\fI\-a\fP] [\fI\-p <pfile>\fP] [\fI\-v <address>\fP] [\fI\-7\fP] \fIfile\fP
+.SH DESCRIPTION
+.sp
+Dis6502 disassembles 6502 binary files. Binary formats understood include
+Atari binary files (L menu command) and boot files. Equate and control
+files can be included via the option to name well known locations and to
+control the disassembly process. The output includes a cross reference.
+.sp
+The disassembly process is a two pass operation: First the program flow
+is traced starting with the init and run parameters in the file headers.
+The dump routine then prints out the information.
+.SH OPTIONS
+.INDENT 0.0
+.TP
+.B \fB\-r\fP \fI<address\fP>
+\fIfile\fP is raw binary, located at \fI<address>\fP\&.
+.TP
+.B \fB\-b\fP
+\fIfile\fP is an Atari boot image (disk or cassette). Note that neither .ATR
+nor .CAS images are supported: the file must be a raw image with no header
+information. For disks, this is called an XFD file.
+.TP
+.B \fB\-l\fP
+\fIfile\fP is an Atari load file (aka XEX).
+.TP
+.B \fB\-c\fP
+\fIfile\fP is a Commodore 64 executable.
+.TP
+.B \fB\-a\fP
+Generate assembly output. Suppresses the addresses and object
+code normally printed on each line of output, and omits the
+cross\-reference section from the end of the output.
+.TP
+.B \fB\-p\fP \fI<pfile>\fP
+Use predefinition file. See \fBFILE FORMAT\fP for the predef file format.
+Up to 10 \fB\-p\fP options may be included.
+.TP
+.B \fB\-v\fP \fI<address>\fP
+Alternate vector address (normally \fB$FFFA\fP). This option only has
+any effect with raw binaries (\fB\-r\fP option).
+.TP
+.B \fB\-7\fP
+Mask character data to 7\-bit.
+.UNINDENT
+.SH FILES
+.sp

+.sp
+\fBlabel\fP .equ \fIaddress\fP
+.INDENT 0.0

+.INDENT 0.0
+.INDENT 3.5
+Defines a table of \fIcount\fP pointers, split into low and
+high byte tables. In assembly code, such a table might look like:
+.INDENT 0.0
+.INDENT 3.5
+.sp
+.nf
+.ft C
+; func1, func2, func3 are addresses.

+.UNINDENT
+.UNINDENT

+To disassemble these, assuming the address of \fItable_lo\fP is \fB$1000\fP,

+DESCRIPTION
+===========

+Dis6502 disassembles 6502 binary files. Binary formats understood include
+Atari binary files (L menu command) and boot files. Equate and control
+files can be included via the option to name well known locations and to
+control the disassembly process. The output includes a cross reference.
+
+The disassembly process is a two pass operation: First the program flow
+is traced starting with the init and run parameters in the file headers.
+The dump routine then prints out the information.
+
+OPTIONS
+=======
+
+**-r** *<address*>
+ *file* is raw binary, located at *<address>*.
+
+**-b**
+ *file* is an Atari boot image (disk or cassette). Note that neither .ATR
+ nor .CAS images are supported: the file must be a raw image with no header
+ information. For disks, this is called an XFD file.
+
+**-l**
+ *file* is an Atari load file (aka XEX).
+
+**-c**
+ *file* is a Commodore 64 executable.
+
+**-a**
+ Generate assembly output. Suppresses the addresses and object
+ code normally printed on each line of output, and omits the
+ cross-reference section from the end of the output.
+
+**-p** *<pfile>*
+ Use predefinition file. See **FILE FORMAT** for the predef file format.
+ Up to 10 **-p** options may be included.
+
+**-v** *<address>*
+ Alternate vector address (normally **$FFFA**). This option only has
+ any effect with raw binaries (**-r** option).
+
+**-7**
+ Mask character data to 7-bit.

+=====
+
+**/usr/share/dis6502/atari8.predef**
+
+**/usr/share/dis6502/c64.predef**
+
+Predefinition files for Atari 8-bit and Commodore 64, containing the usual
+system equates.
+
+FILE FORMAT
+===========
+
+Lines in a predefinition file consist of:
+
+**label** .eq *address*
+
+**label** .equ *address*
+
+ Defines a label. The **.eq** and **.equ** forms are equivalent.
+
+**.jtab2** *lowaddr,hiaddr,count*
+
+ Defines a table of *count* pointers, split into low and
+ high byte tables. In assembly code, such a table might look like::
+
+ ; func1, func2, func3 are addresses.
+ table_lo: .byte <func1, <func2, <func3
+ table_hi: .byte >func1, >func2, >func3
+
+ To disassemble these, assuming the address of *table_lo* is **$1000**,
+ use::
+
+ .jtab2 $1000,$1003,3
+
+**.rtstab** *lowaddr*\,*hiaddr*\,*count*
+
+ Like **.jtab2**, but each entry contains the target address minus one, for use with RTS.
+
+**.trace** *address*
+
+ Causes the trace process to continue at *address*.

+**.stop** *address*
+
+ Causes the trace process to stop at *address*.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct. It's also
+# customary to leave one space after the ':' except on otherwise blank lines.

+dis6502: dis6502 (flow-tracing disassembler for 6502)
+dis6502:
+dis6502: dis6502 is a 6502 disassembler that supports Atari 8-bit and Commodore
+dis6502: executables, as well as raw memory dumps. It attempts to separate code
