24 utility reads a file from stdin and writes it to stdout, converting each
25 byte to its decimal or hexadecimal representation on the fly.
26 The byte values are separated by a comma.
27 This also means that the last byte value is not followed by a comma.
28 By default the byte values are printed in decimal, but when the
30 option is given, the values will be printed in hexadecimal.
32 If more than 70 characters are printed on the same line, that line is
33 ended and the output continues on the next line.
36 option this can be made to happen after the specified number of
37 byte values have been printed.
38 The length of the line will not be considered anymore.
39 To have all the byte values printed on the same line, give the
41 option a negative number.
43 A prefix and suffix strings can be printed before and after the byte values
45 If a suffix is to be printed, a prefix must also be specified.
46 The first non-option word is the prefix, which may optionally be followed
47 by a word that is to be used as the suffix.
49 This program is typically used to embed binary files into C source files.
50 The prefix is used to define an array type and the suffix is used to end
56 options are useful when the binary data represents a bitmap and the output
57 needs to remain readable and/or editable.
58 Fonts, for example, are a good example of this.
