    (description "The two programs are useful for generating test data, for
inspecting binary files, and for interfacing programs that generate textual
output to programs that require binary input and conversely.  They can also be
useful when it is desired to reformat numbers.

@itemize

@item @command{ascii2binary} reads input consisting of ascii or hexadecimal
   representation numbers separated by whitespace and produces as output
   the binary equivalents.  The type and precision of the binary output
   is selected using command line flags.

@item @command{binary2ascii} reads input consisting of binary numbers
   and converts them to their ascii or hexadecimal representation.
   Command line flags specify the type and size of the binary numbers
   and provide control over the format of the output.
   Unsigned integers may be written out in binary, octal, decimal,
   or hexadecimal.

   Signed integers may be written out only in binary or decimal.  Floating
   point numbers may be written out only decimal, either in standard or
   scientific notation.  (If you want to examine the binary representation
   of floating point numbers, just treat the input as a sequence of unsigned
   characters.)

@itemize

@item @command{uniname} defaults to printing the character offset of each
character, its byte offset, its hex code value, its encoding, the glyph
itself, and its name.  It may also be used to validate UTF-8 input.

@item @command{unidesc} reports the character ranges to which different
portions of the text belong.   It can also be used to identify Unicode encodings
(e.g. UTF-16be) flagged by magic numbers.

@item @command{unihist} generates a histogram of the characters in its input.

@item @command{ExplicateUTF8} is intended for debugging or for learning about
Unicode.  It determines and explains the validity of a sequence of bytes as a
UTF8 encoding.

@item @command{utf8lookup} provides a handy way to look up Unicode characters
from the command line.

@item @command{unireverse} reverse each line of UTF-8 input
character-by-character.

@table @command
@item accudate
An extended version of the \"date\" program that has sub-second accuracy.
@item binformat
Format complex binary data into text.
@item binload
Load data into a binary file using simple commands from the input.
@item binorder
Sort, merge, search, retrieve or generate test data consisting of fixed size
binary records.
@item binreplace
Find or find/replace in binary files.
@item binsplit
Split test data consisting of fixed size binary records into one or more
output streams.
@item chardiff
Find changes between two files at the character level.  Unlike \"diff\", it
lists just the characters that differ, so if the 40,000th character is
different only that one character will be shown, not the entire line.
@item columnadd
Add columns of integers, decimals, and/or times.
@item datasniffer
A utility for formatting binary data dumps.
@item dmath
Double precision interactive command line math calculator.
@item extract
Extract and emit data from text files based on character or token position.
@item execinput
A utility that reads from STDIN and executes each line as a command in a
sub-process.
@item indexed_text
A utility for rapid retrieval of text by line numbers, in any order, from a
text file.
@item mdump
Format binary data.
@item msgqueue
Create message queues and send/receive messages.
@item mbin
@itemx mbout
Multiple buffer in and out.  Used for buffering a lot of data between a slow
device and a fast device.  Mostly for buffering streaming tape drives for use
with slower network connections, so that streaming is maintained as much as
possible to minimize wear on the tape device.
@item pockmark
Corrupt data streams - useful for testing error correction and data recovery.
@item tarsieve
Filter, list, or split a tar file.

input formats into a wide range of output formats.  To alter the
exported output document, Pandoc allows the usage of filters, which
are pipes that read a JSON serialization of the Pandoc AST from stdin,
transform it in some way, and write it to stdout.  It allows therefore
to alter the processing of Pandoc's supported input formats, for
instance one can add new syntax elements to markdown, etc.

This package provides Python bindings.")
