-See README_SBo.txt for build options. The defaults should be fine for
-most users.
+This build includes both the GTK+3 and SDL2[*] menu-based user
+interfaces. The SDL2 binaries are installed with -sdl2 suffix,
+e.g. x64-sdl2 and x128-sdl2.
+
+[*] If you'd rather build with SDL 1.x for some reason, set SDL=1 in
+the environment. The SDL1 binaries are installed with -sdl1 suffix.
+It's also possible to omit the SDL binaries entirely with SDL=no.
+
+To build without PulseAudio, set PULSE=no in the environment.

-Optional dependencies: ffmpeg and SDL2.
-
-Vice can use ffmpeg to record videos of the emulated machine. If
-ffmpeg is installed, it will be autodetected. If you have ffmpeg
-installed but don't want ffmpeg support, you'll have to removepkg
-ffmpeg before building (there's no way to override the autodetection).
-
-By default, vice will be built with SDL2 if it's installed, otherwise
-SDL1. You can set SDL=1 to force building with SDL1 even if SDL2 is
-installed.
-
-If you want to build without PulseAudio, set PULSE=no in the environment.
-
-Note: To use the standard application menu instead of the in-emulator
-PETSCII menu, GTK3 v3.22 is required. Slackware 14.2 ships with 3.18
-and there is no upgrade package for this. Slackware -current has
-3.22. So to use the normal application menus, either use Slackware
--current or find a way to upgrade your Slackware 14.2's GTK3 to
-v3.22. The SlackBuild maintainer has NOT tested this build with
-Slackware -current, you're on your own if it doesn't work (fix it and
-send me a patch if you can).

+.SH DESCRIPTION
+.IR petcat
+converts input files from the most common CBM file formats into
+printable ASCII form and writes to standard output. The type
+of input file is determined automatically, if possible, and
+appropriate conversion is performed.
+Since a few of the BASIC versions have keywords defined differently,
+the right conversion has to be selected on the command line.
+Where such confusion cannot happen, automatical recognition of input
+is used. This is useful when expanding several files at once or if
+the program contains code for several versions, selected according to
+the hardware; eg. Simons' Basic vs. Basic 7.0.
+.br
+Please note that each input file is converted individually,
+but the output is produced as continuous flow. Also, all input
+files that are read trough a pipe, are concatenated before they
+reach
+.IR petcat
+so any machine language section in between the BASIC programs causes
+all consecutive files to be taken as one machine language program.
+For that reason files containing machine language parts attached to
+them must be input separately, otherwise the remaining files won't
+be expanded.
+.IR petcat
+recognizes normal PETSCII text files (SEQ), program files containing
+directory listing, and BASIC programs. Both the original CBM files and
+files with a PC64 `P00' header are accepted. The different BASIC versions
+are not automatically distinguished, but standard C64 and C128 versions
+are used as default.
+.br
+In order to tokenize a text file into a BASIC binary file the desired
+BASIC version must be exclusively specified so that correct set of
+keywords will be used.
+If line numbers are not found in the beginning of each program line,
+the cruncher creates the missing line numbers by adding 2 to the numeric
+value of previous one.
+Since also line numbers deviating from strictly ascendind order are
+accepted, care must be taken when editing such a program on a C64 again.
+.SS Clarification
+.LP
+Since CBM programs usually contain unprintable characters, a way to
+specify them has been created.
+Normally,
+.IR petcat
+uses the same codes as most printers, but for tokenizing programs
+scanned from magazines, it can use the following convention:
+.br
+.TP 12
+.BR "{DOWN}"
+stands for single control code
+.TP
+.BR "{6 RIGHT}"
+contains amout of consecutive codes
+.TP
+List of valid mnemonics:
+.br
+{wht} {dish} {ensh} {swlc} {down} {rvon} {home} {del} {esc} {red}
+{rght} {grn} {blu} {orng} {F1} {F3} {F5} {F7} {F2} {F4} {F6} {F8}
+{sret} {swuc} {blk} {up} {rvof} {clr} {inst} {brn} {lred} {gry1}
+{gry2} {lgrn} {lblu} {gry3} {pur} {left} {yel} {cyn}
+.TP
+List of alternate mnemonics:
+.br
+{wht} {up/lo lock on} {up/lo lock off} {return} {lower case} {down}
+{rvs on} {home} {delete} {esc} {red} {right} {grn} {blu} {orange}
+{f1} {f3} {f5} {f7} {f2} {f4} {f6} {f8} {shift return} {upper case}
+{blk} {up} {rvs off} {clr} {insert} {brown} {lt red} {grey1} {grey2}
+{lt green} {lt blue} {grey3} {pur} {left} {yel} {cyn}
+.SH OPTIONS
+.TP 8
+.B \-l \fIload_address\fR
+Specify \fIload_address\fR (in hex) for tokenized program.
+.TP
+.B \-c
+Causes
+.IR petcat
+to interpret also control characters.
+By default, these strings are the same as used by printers. However,
+an alternate set is attempted whenever none within the primary set
+matches. Default is ON, unless text mode is selected.
+.TP
+.B \-nc
+Suppress control codes.
+.TP
+.B \-f
+Force overwrite of existing output file. Default true.
+.TP
+.B \-h
+Print filename and start address for each Basic file expanded. Default true.
+.TP
+.B \-nh
+Suppress file header in printout.
+.TP
+.B \-o \fIfile\fR
+Redirect output to the specified \fIfile\fR. This option overrules -h.
+When \fIfile\fP has extension `.P00' and also -w option is specified, the PC64
+file header is written automatically. .P00 file cannot be written on stdout
+but to a file only.
+.TP
+.B \-skip \fIoffset\fR
+Skip \fIoffset\fR bytes in the beginning of input file.
+.TP
+.B \-text
+Force text mode even if the input file looks like a Basic program, i.e.
+the first byte in file is 01.
+.TP
+.B \-k<\fIversion\fR>
+Just prints all valid keywords for the specified Basic \fIversion\fR.
+Without any \fIversion\fR, all names of supported BASIC versions are
+listed instead.
+.TP
+.B \-w<\fIversion\fR>
+Tokenise program listing using keywords set from the specified Basic
+\fIversion\fR.
+.TP
+\-<\fIversion\fR>
+Changes the set of keywords for the specified Basic \fIversion\fR and
+expands tokenized input file.
+Without this option
+.IR petcat
+uses V7.0 keywords in expanding.
