+=head1 NAME
+
+unzpaq - PAQ open standard maximum compressor unpacker
+
+=head1 SYNOPSIS
+
+ list : unzpaq l archive.zpaq
+ extract: unzpaq x archive.zpaq [file ...]
+
+=head1 DESCRIPTION
+
+=head2 General
+
+PAQ is a series of open source data compression archivers that have
+evolved through collaborative development to top rankings on several
+benchmarks measuring compression ratio although at the expense of
+speed and memory usage.
+
+Zpaq ia a proposed standard format for highly compressed data that
+allows new compression algorithms to be developed without breaking
+compatibility with older programs. Zpaq is based on PAQ-like context
+mixing algorithms which are top ranked on many benchmarks. The format
+supports archivers, single file compressors, and memory to memory
+compression.
+
+I<NOTE:> in extract mode, if the FILES are listed the files are
+renamed during written out.
+
+=head2 Commands
+
+=over 4
+
+=item B<l>
+
+List contents of archive.
+
+=item B<x>
+
+Extract. Use "ox" to extract fast. You can extract more slowly with
+plain "x" if you don't have C++ installed. Output files are renamed in
+the same order they are stored and listed. If you don't rename the
+output files, then the files will be extracted to the current
+directory with the same names they had when stored.
+
+=back
+
+=head1 OPTIONS
+
+None.
+
+=head1 EXAMPLES
+
+To list the contents of an archive. Files are listed in the same order
+they were added:
+
+ zpaq l archive.zpaq
+
+To extract the contents of the archive. New files are created and
+named according to the stored filenames. Does not clobber existing
+files. Extracts to current directory:
+
+ zpaq x archive.zpaq
+
+If the files to be extracted already exist, then zpaq will
+refuse to clobber them and skip to the next file. If the files
+are compressed with a path (folder or directory), then that
+directory must exist when the file is extracted. zpaq will
+not create directories.
+
+To extract files and renames in the order they were added to the
+archive. Clobbers any already existing output files. The number of
+files extracted is the smaller of the number of filenames on the
+command line or the number of files in the archive.
+
+ zpaq x archive.zpaq file ...
+
+To extract and rename:
+
+ zpaq x archive.zpaq files ...
+ unzpaq x archive.zpaq files ...
+
+Files are extracted in the same order they are saved and renamed.
+Unlike using stored names, if the file exists, then it is
+overwritten (clobbered). Only files named on the command line
+are extracted. Any additional files in the archive are ignored.
+For example:
+
+ zpaq x archive.zpaq foo bar
+
+=head1 ENVIRONMENT
+
+None.
+
+=head1 FILES
+
+None.
+
+=head1 STANDARDS
+
+See zpaq*.pdf (ZPAQ Level 1 and later) in section AVAILABILITY . It is
+anticipated that future levels (ZPAQ-2, ZPAQ-3, etc.) will be backward
+compatible, such that newer levels can read archives produced by older
+programs.

+=head1 DESCRIPTION
+
+=head2 General
+
+PAQ is a series of open source data compression archivers that have
+evolved through collaborative development to top rankings on several
+benchmarks measuring compression ratio although at the expense of
+speed and memory usage.
+
+Zpaq ia a proposed standard format for highly compressed data that
+allows new compression algorithms to be developed without breaking
+compatibility with older programs. Zpaq is based on PAQ-like context
+mixing algorithms which are top ranked on many benchmarks. The format
+supports archivers, single file compressors, and memory to memory
+compression.
+
+ZPAQ is a configurable file compressor and archiver. Its goal
+is a high compression ratio in an open format without loss of
+compatibility between versions as advanced compression techniques
+are discovered.
+
+Compression uses by default built-in configuration files. Three
+examples are supplied:
+
+ min.cfg - Fast, minimal compression (LZP + order 3). Requires 4 MB memory.
+ mid.cfg - Average compression and speed. Requires 111 MB.
+ max.cfg - Slow but good compression. Requires 278 MB.
+
+The config file is not needed to extract.
+
+NOTE: in extract mode, if the FILES are listed the files are renamed
+during written out.
+
+head2 Commands
+
+=over 4
+
+=item B<a>
+
+Append to archive.
+
+=item B<c>
+
+Create archive.
+
+=item B<i>
+
+Don't store file sizes as comments (saves a few bytes). Normally the
+input file size is stored as a decimal string, taking a few bytes. The
+comment field has no effect on the program except that it is displayed
+by the B<l> and B<x> commands.
+
+=item B<l>
+
+List contents of archive.
+
+=item B<n>
+
+I<In create mode>: Don't store filenames (names will be needed to
+decompress). I<In extract mode>: decompress all to one file. The
+effect is to require that filenames be given during decompression.
+
+During extract ignore all stored filenames and append all output to
+one file, the first file in [files...].
+
+=item B<o>
+
+Optimize (run faster). You need a C++ compiler installed to use this
+option. If not, drop the "o". You can still use zpaq but it will take
+about twice as long to run.
+
+If successful, compression is typically 50% to 100% faster. Zpaq will
+look for a program named C<zpaq_X> in the temporary directory, where X
+is derived from the SHA1 checksum of the block header produced by
+config file I<CONFIG> with arguments I<N>. If the program exists, then
+Zpaq will call it with the same arguments to perform the compression.
+If it does not exist then Zpaq will create a source code file
+C<zpaq_X.cpp> in the temporary directory, compile it, and link it to
+C<zpaq.cpp> or C<zpaq.o> depending on the installation.
+
+The temporary directory is specified by the environment variable
+TEMP if it exists, or else the current directory.
+
+The program C<zpaq_X> will compress its input in the same format as
+described by I<CONFIG>, but faster. If I<CONFIG> specifies a
+preprocessor, then C<zpaq_X> will expect to find it too. It will also
+decompress archive blocks in the same configuration but fail if it
+attempts to decompress blocks in any other configuration.
+
+Program C<zpaq_X> will accept the B<c>, B<a> and B<x> commands with
+all of the same modifiers, but will ignore the B<v> and B<o> modifiers
+and ignore any CONFIG file and arguments passed to it. It will not
+accept the B<l> or B<r> commands. Extraction requires a block number
+("x1", "x2", etc). A different optimized program is used to extract
+each block.
+
+Zpaq will call the external program C<zpaqmake> to compile
+C<zpaq_X.cpp>, passing it C<zpaq_X> as an argument. Normally this will
+be a script that calls a C++ compiler to produce C<zpaq_X.o>, links to
+C<zpaq.o> and outputs C<zpaq_X>. The script could link to C<zpaq.cpp>
+instead of C<zpaq.o>.
+
+=item B<p>
+
+I<In create mode>: Store filename paths in archive. The default is to
+store the name without the path. For example:
+
+ zpaq pc<CONFIG> books.zpaq dir/file
+
+will store the name as C<dir/file>. If the B<p> option is also given
+during extraction, then ZPAQ will attempt to extract C<file> to the
+subdirectory instead of the current directory. This will fail if
+directory does not exist. ZPAQ does not create directories as needed.
+
+I<In extract mode>: extract to stored paths instead of current
+directory
+
+The default is to extract to the current directory regardless of how
+the file names are stored. Stored paths must be relative to the
+current directory, not start with a "/", "\", a drive letter like "C:"
+or contain "../" or "..\". If extracting to a subdirectory, it must
+already exist. It will not be created.
+
+[files...] overrides and has no restrictions on file names. Each
+segment extracts to a different file. If any segments do not have a
+stored filename then they can only be extracted using the B<p> or B<n>
+modifiers.
+
+=item B<q>
+
+Quiet mode. Don't display compression progress on the screen.
+
+=item B<s>
+
+Don't store SHA1 checksums (saves 20 bytes).The decompressor will not
+check that the output is identical to the original input.
+
+=item B<t>
+
+I<In create mode>: Append locator tag to non-ZPAQ data.
+
+Append a locator tag to non-ZPAQ data. The tag is a string of 13 bytes
+that allows ZPAQ and UNZPAQ to find the start of a sequence of ZPAQ
+blocks embedded in other data. Program C<zpaqsfx> already has this tag
+at the end. However, if a new stub is compiled from the source then
+the B<t> command should be used when appending the first file.
+
+I<In extract mode>: don't post-process (for debugging). Expect
+checksum errors.
+
+=item B<v>
+
+Verbose mode. Show CONFIG file as it compiles. This is useful for
+error checking.
+
+=item B<x>
+
+Extract. Use "ox" to extract fast. You can extract more slowly with
+plain "x" if you don't have C++ installed. Output files are renamed in
+the same order they are stored and listed. If you don't rename the
+output files, then the files will be extracted to the current
+directory with the same names they had when stored.
+
+=item B<,N>
+
+Usd in create mode. Pass numeric arguments to CONFIG file. Appended
+suffix like ",2" means use 4 times more memory. Each increment doubles
+usage. You need the same memory to decompress.
+
+=item B<N>
+
+I<Used in extract mode>. Extract only block N (1, 2, 3...), where 1 is
+the first block. Otherwise all blocks are extracted. The B<l> command
+shows which files are in each block.
+
+=back
+
+=head2 Debug and Development Options
+
+To debug CONFIG file, use:
+
+ zpaq [pthv]r<CONFIG>[,N...] [args...]
+
+the B<r> runn the ZPAQL program in HCOMP section of configuration file
+F. The program is run once for each byte of input from the file named
+in the first argument and once at EOF with the input byte (or -1) in
+the A register. Output is to the file named in the second argument. If
+run with no arguments then take input from stdin and output to stdout.
+Modifiers are listed below.
+
+=over 4
+
+=item B<h>
+
+When tracing, display register and memory contents in hexadecimal
+instead of decimal.
+
+=item B<p>
+
+Run PCOMP (default is to run HCOMP).
+
+=item B<t>
+
+Trace (single step), args are numeric inputs otherwise args are input,
+output (default stdin, stdout). The arguments should be numbers rather
+than file names. The program is run once for each argument with the
+value in the A register. As each instruction is executed the register
+contents are shown. At HALT, memory contents are displayed.
+
+=item B<v>
+
+Verbose compile. Display the CONFIG file as it is being compiled. If
+an error occurs, it will be easier to locate. Modifier B<v> is also
+useful for displaying jump targets.
+
+=item B<,N>
+
+Pass numeric arguments to CONFIG file. Pass up to 9 numeric arguments
+to CONFIG file (like the B<c> and B<a> commands).

+=head1 EXAMPLES
+
+=head2 Create
+
+To create an archive:

+ zpaq c<CONFIG> archive.zpaq files ...
+
+If the archive exists then it is overwritten. File names are stored
+without a path.
+
+=head2 Append
+
+To (a)ppend to an existing archive. If the archive does not exist then

+=head2 List
+
+To list the contents of an archive. Files are listed in the same order
+they were added:
+
+ zpaq l archive.zpaq
+
+To extract the contents of the archive. New files are created and
+named according to the stored filenames. Does not clobber existing

+If the files to be extracted already exist, then zpaq will
+refuse to clobber them and skip to the next file. If the files
+are compressed with a path (folder or directory), then that
+directory must exist when the file is extracted. zpaq will
+not create directories.
+
+To extract files and renames in the order they were added to the
+archive. Clobbers any already existing output files. The number of

+To extracts files like B<x>, but without post-processing. This may be
+useful for debugging or developing config files:
+
+ zpaq t archive.zpaq [files ...]
+
+=head2 Config file
+
+The distribution contain several default CONFIG files:
+
+ min.cfg - for fast but poor compression.
+ max.cfg - for slow but good compression.
+ mid.cfg - for moderate speed and compression (default).
+
+Other config files are available as add-on options or you can write
+them as explained later.
+
+A numeric argument may be appended to CONGIF to increase memory usage
+for better compression. Each increment doubles usage. There should be
+no space before or after the comma. For example:
+
+ zpaq cmax.cfg archive files... = 246 MB
+ zpaq cmax.cfg,1 archive files... = 476 MB
+ zpaq cmax.cfg,2 archive files... = 938 MB
+ zpaq cmax.cfg,3 archive files... = 1861 MB
+ zpaq cmax.cfg,-1 archive files... = 130 MB (negative values allowed)
+
+Modifiers may be in any order before the "c" or "a" command. The
+modifiers, command, and configuration file must be written together
+without any spaces. An example: to create archive with options B<i, p,
+s> and configuration file C<max.cfg>. Modifiers have the following
+meaning:
+
+ zpaq ipsc<CONFIG> archive.zpaq file1 file22
+
+=head1 ENVIRONMENT
+
+Temporary directory B<TEMPDIR> is use during optimize command B<o>.
+
+None.
+
+=head1 FILES
+
+Compression commands B<c> and B<a> need a configuration file. See examples in
+directory C</usr/share/doc/zpaq>.
+
+=head1 STANDARDS
+
+See zpaq*.pdf (ZPAQ Level 1 and later) in section AVAILABILITY . It is
+anticipated that future levels (ZPAQ-2, ZPAQ-3, etc.) will be backward
+compatible, such that newer levels can read archives produced by older
+programs.
