+pucrunch (compressor optimized for low-resource decompression)
+
+Pucrunch is a Hybrid LZ77 and RLE compressor, uses an Elias Gamma Code
+for lengths, mixture of Gamma Code and linear for LZ77 offset, and
+ranked RLE bytes indexed by the same Gamma Code. Uses no extra memory
+in decompression.
+
+The compressor can compress/decompress files for C64 (-c64), VIC20
+(-c20), C16/+4 (-c16), or for standalone decompressor (-c0).
+
+Assembly sources for example decompressors (for Commodore 64 and Nintendo
+GameBoy) are included.

+.SH SYNOPSIS
+.sp
+cbmcombine [\fIinput\-file[,load\-address]\fP] [[[\fIinput\-file[,load\-address]\fP]] ...]
+.SH DESCRIPTION
+.sp
+cbmcombine combines several Commodore executables into one. All Commodore
+8\-bit machines (64, 128, VIC\-20, Plus4, 16, PET, etc) are supported,
+since they all use the same executable file format.
+.sp
+Files are read in the order listed on the command line. The combined
+executable is written to standard output. Each file\(aqs load address can
+be forced by adding a comma and the new address (in decimal, or in hex
+with 0x prefix), in which case the load address in the file will be read
+and ignored.
+.sp
+If any of the input files overlap the same area of memory, the overlap
+area will contain only data from the file(s) listed later in the command
+line. The output file\(aqs load address will be that of the input file with
+the lowest address, and it will extend to the highest address contained
+in any of the files. If there are gaps in the address space (areas where
+no file was loaded), the output will contain 0x00 bytes to fill the gap.
+.sp
+Load address overrides do NOT relocate code.
+.sp
+There are no switches (options) for cbmcombine.
+.SH EXAMPLES
+.sp
+The examples use 1024 byte input files, named after their load addresses
+in hex:
+.sp
+x1000.prg   Load address \fB$1000\fP, last address \fB$13FF\fP
+.sp
+x1400.prg   Load address \fB$1400\fP, last address \fB$17FF\fP
+.sp
+x1600.prg   Load address \fB$1600\fP, last address \fB$19FF\fP
+.sp
+cmbcombine x1000.prg x1400.prg > new.prg
+.INDENT 0.0
+.INDENT 3.5
+new.prg will have a load address of 0x1000, and contain data from
+0x1000 to 0x17ff.  Since x1000.prg ends at address 0x13ff, there is
+no overlap. If the order of arguments were swapped, the result would
+be the same.

+
+EXAMPLES
+========
+
+The examples use 1024 byte input files, named after their load addresses

+
+cmbcombine x1400.prg x1600.prg > new.prg
+
+  new.prg's load address will be **$1400** and it will end at **$19FF**. The
+  data from **$1400** to **$15FF** comes from x1400.prg, and the rest from x1600.prg.
+
+cmbcombine x1600.prg x1400.prg > new.prg
+
+  As above, but data at **$1400** to **$15FF** comes from x1400.prg.
+
+cmbcombine x1400.prg x1600.prg,0x1800 > new.prg
+
+  new.prg loads at **$1400** and extends to **$1BFF**. Data at **$1400** to
+  **$17FF** comes from x1400.prg, data at **$1800** to **$1BFF** comes from
+  x1600.prg. If x1600.prg contains non-relocatable code org'ed at **$1600**,
+  it will fail to run when loaded at **$1800**.
+
+EXIT STATUS
+===========
+
+0 for success, non-zero for failure. If any of the input files can't be
+read, the process exits with failure status, without writing anything
+to standard output.
+
+BUGS
+====
+
+There is very little error-checking. It may be possible to crash
+cbmcombine by feeding it bogus input.
+
+There's no way to give cbmcombine a filename containing a comma.
+

+.SH SYNOPSIS
+.sp
+pucrunch [\fI\-options\fP] [\fIinfile]\fP [\fIoutfile\fP]]
+.SH DESCRIPTION
+.sp
+Pucrunch is a Hybrid LZ77 and RLE compressor, uses an Elias Gamma Code
+for lengths, mixture of Gamma Code and linear for LZ77 offset, and
+ranked RLE bytes indexed by the same Gamma Code. Uses no extra memory
+in decompression.
+.sp
+Input files can be arbitrary data (with \fI\-d\fP option) or executables for
+Commodore 64, VIC\-20, C16, or Plus/4. Output is either a self\-extracting
+compressed Commodore executable, or a compressed data file suitable for
+extracting via \fIpucrunch \-u\fP or the included decompressor routines. See
+/usr/doc/pucrunch\-20081122/examples/*.asm for 6502, 6809, and Z80
+assembly code implementations of the decompressor.
+.sp
+Note: Because pucrunch contains both RLE and LZ77 and they are
+specifically designed to work together, DO NOT RLE\-pack your files
+first, because it will decrease the overall compression ratio.
+.SH OPTIONS
+.sp
+Pucrunch expects any number of options and up to two filenames. If you
+only give one filename, the compressed file is written to the stardard
+output. If you leave out both filenames, the input is in addition
+read from the standard input. Options needing no value can be grouped
+together. All values can be given in decimal (no prefix), octal (prefix
+0), or hexadecimal (prefix $ or 0x). [\fINote\fP: escape the \fI$\fP with quotes
+or a backslash, to avoid your shell treating it as a metacharacter]
+.sp
+Example: pucrunch demo.prg demo.pck \-m6 \-fs \-p2 \-x0xc010
+.INDENT 0.0
+.TP
+.B \fB\-c<machine>\fP
+Selects the machine. Possible values are 128 (C128), 64 (C64),
+20 (VIC20), 16 (C16/Plus4), 0 (standalone). The default is 64, i.e.
+Commodore 64.
+.sp
+If you use \-c0, a file without the embedded decompression code
+is produced. This can be decompressed with a standalone routine
+and of course with pucrunch itself. Options marked with [\fISFX\fP]
+have no effect if \-c0 is used.
+.sp
+The 128\-mode is not fully developed yet. Currently it overwrites
+memory locations $f7\-$f9 (Text mode lockout, Scrolling, and Bell
+settings) without restoring them later.
+.TP
+.B \fB\-a\fP
+[\fISFX\fP] Avoids video matrix if possible. Only affects VIC20 mode.
+.TP
+.B \fB\-d\fP
+[\fISFX\fP] Indicates that the file does not have a load address. A load
+address can be specified with \-l option. The default load
+address if none is specified is 0x258.
+.TP
+.B \fB\-l<addr>\fP
+[\fISFX\fP] Overrides the file load address or sets it for data files.
+.TP
+.B \fB\-x<addr>\fP
+[\fISFX\fP] Sets the execution address or overrides automatically detected
+execution address. Pucrunch checks whether a SYS\-line is present
+and tries to decode the address. Plain decimal addresses and
+addresses in parenthesis are read correctly, otherwise you need
+to override any incorrect value with this option.
+.TP
+.B \fB\-e<val>\fP
+Fixes the number of escape bits used. You don\(aqt usually need or
+want to use this option.
+.TP
+.B \fB\-r<val>\fP
+Sets the LZ77 search range. By specifying 0 you get only RLE.
+You don\(aqt usually need or want to use this option.
+.TP
+.B \fB+f\fP
+Disables 2MHz mode for C128 and 2X mode in C16/+4.
+.TP
+.B \fB\-fbasic\fP
+[\fISFX\fP] Selects the decompressor for basic programs. This version
+performs the RUN function and enters the basic interpreter
+automatically. Currently only C64 and VIC20 are supported.
+.TP
+.B \fB\-ffast\fP
+[\fISFX\fP] Selects the faster, but longer decompressor version, if such
+version is available for the selected machine and selected
+options. Without this option the medium\-speed and medium\-size
+decompressor is used.
+.TP
+.B \fB\-fshort\fP
+[\fISFX\fP] Selects the shorter, but slower decompressor version, if such
+version is available for the selected machine and selected
+options. Without this option the medium\-speed and medium\-size
+decompressor is used.
+.TP
+.B \fB\-flist\fP
+List all available decompressors (the \fI\-f\fP options above), for all
+supported machines. The list may contain more decompressors than are
+shown above (the extras might be experimental, use at your own risk).
+.TP
+.B \fB\-fdelta\fP
+Allows delta matching. In this mode only the waveforms in the
+data matter, any offset is allowed and added in the
+decompression. Note that the decompressor becomes 22 bytes
+longer if delta matching is used and the short decompressor
+can\(aqt be used (24 bytes more). This means that delta matching
+must get more than 46 bytes of total gain to get any net
+savings. So, always compare the result size to a version
+compressed without \-fdelta.
+.sp
+Also, the compression time increases because delta matching is
+more complicated. The increase is not 256\-fold though, somewhere
+around 6\-7 times is more typical. So, use this option with care
+and do not be surprised if it doesn\(aqt help on your files.
+.TP
+.B \fB\-n\fP
+Disables RLE and LZ77 length optimization. You don\(aqt usually
+need or want to use this option.
+.TP
+.B \fB\-s\fP
+Display full statistics instead of a compression summary.
+.TP
+.B \fB\-p<bits>\fP
+Fixes the number of extra LZ77 position bits used for the low
+part. If pucrunch tells you to to use this option, see if the
+new setting gives better compression.
+.TP
+.B \fB\-m<bits>\fP
+Sets the maximum length value. The value should be 5, 6, or 7.
+The lengths are 64, 128 and 256, respectively. If pucrunch tells
+you to to use this option, see if the new setting gives better
+compression. The default value is 7.
+.TP
+.B \fB\-i<0|1>\fP
+Defines the interrupt enable state to be used after
+decompression. Value 0 disables interrupts, other values enable
+interrupts. The default is to enable interrupts after
+decompression.
+.TP
+.B \fB\-g<byte>\fP
+Defines the memory configuration to be used after decompression.
+Only used for C64 mode (\-c64). The default value is $37.
+.TP
+.B \fB\-u\fP
+Unpacks/decompresses a file instead of compressing it. The file
+to decompress must have a decompression header compatible with
+one of the decompression headers in the current version.
+.TP
+.B \fB\-h\fP
+Print built\-in help and exit.

+SYNOPSIS
+========
+
+pucrunch [*-options*] [*infile]* [*outfile*]]
+
+DESCRIPTION
+===========
+
+Pucrunch is a Hybrid LZ77 and RLE compressor, uses an Elias Gamma Code
+for lengths, mixture of Gamma Code and linear for LZ77 offset, and
+ranked RLE bytes indexed by the same Gamma Code. Uses no extra memory
+in decompression.
+
+Input files can be arbitrary data (with *-d* option) or executables for
+Commodore 64, VIC-20, C16, or Plus/4. Output is either a self-extracting
+compressed Commodore executable, or a compressed data file suitable for
+extracting via *pucrunch -u* or the included decompressor routines. See
+/usr/doc/pucrunch-|version|/examples/\*.asm for 6502, 6809, and Z80
+assembly code implementations of the decompressor.
+
+Note: Because pucrunch contains both RLE and LZ77 and they are
+specifically designed to work together, DO NOT RLE-pack your files
+first, because it will decrease the overall compression ratio.
+
+OPTIONS
+=======
+
+Pucrunch expects any number of options and up to two filenames. If you
+only give one filename, the compressed file is written to the stardard
+output. If you leave out both filenames, the input is in addition
+read from the standard input. Options needing no value can be grouped
+together. All values can be given in decimal (no prefix), octal (prefix
+0), or hexadecimal (prefix $ or 0x). [*Note*: escape the *$* with quotes
+or a backslash, to avoid your shell treating it as a metacharacter]
+
+Example: pucrunch demo.prg demo.pck -m6 -fs -p2 -x0xc010
+
+**-c<machine>**
+       Selects the machine. Possible values are 128 (C128), 64 (C64),
+       20 (VIC20), 16 (C16/Plus4), 0 (standalone). The default is 64, i.e.
+       Commodore 64.
+
+       If you use -c0, a file without the embedded decompression code
+       is produced. This can be decompressed with a standalone routine
+       and of course with pucrunch itself. Options marked with [*SFX*]
+       have no effect if -c0 is used.
+
+       The 128-mode is not fully developed yet. Currently it overwrites
+       memory locations $f7-$f9 (Text mode lockout, Scrolling, and Bell
+       settings) without restoring them later.
+
+**-a**
+       [*SFX*] Avoids video matrix if possible. Only affects VIC20 mode.
+
+**-d**
+       [*SFX*] Indicates that the file does not have a load address. A load
+       address can be specified with -l option. The default load
+       address if none is specified is 0x258.
+
+**-l<addr>**
+       [*SFX*] Overrides the file load address or sets it for data files.
+
+**-x<addr>**
+       [*SFX*] Sets the execution address or overrides automatically detected
+       execution address. Pucrunch checks whether a SYS-line is present
+       and tries to decode the address. Plain decimal addresses and
+       addresses in parenthesis are read correctly, otherwise you need
+       to override any incorrect value with this option.
+
+**-e<val>**
+       Fixes the number of escape bits used. You don't usually need or
+       want to use this option.
+
+**-r<val>**
+       Sets the LZ77 search range. By specifying 0 you get only RLE.
+       You don't usually need or want to use this option.
+
+**+f**
+       Disables 2MHz mode for C128 and 2X mode in C16/+4.
+
+**-fbasic**
+       [*SFX*] Selects the decompressor for basic programs. This version
+       performs the RUN function and enters the basic interpreter
+       automatically. Currently only C64 and VIC20 are supported.
+
+**-ffast**
+       [*SFX*] Selects the faster, but longer decompressor version, if such
+       version is available for the selected machine and selected
+       options. Without this option the medium-speed and medium-size
+       decompressor is used.
+
+**-fshort**
+       [*SFX*] Selects the shorter, but slower decompressor version, if such
+       version is available for the selected machine and selected
+       options. Without this option the medium-speed and medium-size
+       decompressor is used.
+
+**-flist**
+       List all available decompressors (the *-f* options above), for all
+       supported machines. The list may contain more decompressors than are
+       shown above (the extras might be experimental, use at your own risk).
+
+**-fdelta**
+       Allows delta matching. In this mode only the waveforms in the
+       data matter, any offset is allowed and added in the
+       decompression. Note that the decompressor becomes 22 bytes
+       longer if delta matching is used and the short decompressor
+       can't be used (24 bytes more). This means that delta matching
+       must get more than 46 bytes of total gain to get any net
+       savings. So, always compare the result size to a version
+       compressed without -fdelta.
+
+       Also, the compression time increases because delta matching is
+       more complicated. The increase is not 256-fold though, somewhere
+       around 6-7 times is more typical. So, use this option with care
+       and do not be surprised if it doesn't help on your files.
+
+**-n**
+       Disables RLE and LZ77 length optimization. You don't usually
+       need or want to use this option.
+
+**-s**
+       Display full statistics instead of a compression summary.
+
+**-p<bits>**
+       Fixes the number of extra LZ77 position bits used for the low
+       part. If pucrunch tells you to to use this option, see if the
+       new setting gives better compression.
+
+**-m<bits>**
+       Sets the maximum length value. The value should be 5, 6, or 7.
+       The lengths are 64, 128 and 256, respectively. If pucrunch tells
+       you to to use this option, see if the new setting gives better
+       compression. The default value is 7.
+
+**-i<0|1>**
+       Defines the interrupt enable state to be used after
+       decompression. Value 0 disables interrupts, other values enable
+       interrupts. The default is to enable interrupts after
+       decompression.
+
+**-g<byte>**
+       Defines the memory configuration to be used after decompression.
+       Only used for C64 mode (-c64). The default value is $37.
+
+**-u**
+       Unpacks/decompresses a file instead of compressing it. The file
+       to decompress must have a decompression header compatible with
+       one of the decompression headers in the current version.
+
+**-h**
+       Print built-in help and exit.

+# 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.
