+Convert Atari 8-bit text to UTF-8 encoded Unicode (and back).

+SYNOPSIS
+========
+
+*a8cat* [**-r**] [**-i**] [**-u**] [**-t**] [*infile*] [*infile ...*]
+
+DESCRIPTION
+===========
+
+Convert Atari 8-bit ATASCII or XL ICS (International Character
+Set) text to UTF-8 encoded Unicode. Control graphics characters are
+replaced with their nearest Unicode equivalents (mostly from the Box
+Drawing block, or from the Basic Latin block with **-i** option).
+
+If no *infile*\s are given, input is read from standard input. Output always
+goes to standard output; to write to a file, use a command like::
+
+  a8cat atari.txt > converted.txt
+
+The output is UTF-8 Unicode, without BOM, but possibly with
+ANSI/VT-100 control sequences. It will display correctly in modern
+terminals that support Unicode and UTF-8. If you get lots of "empty
+rectangle" characters, it means your font lacks the glyphs for the
+codepoints; try using the Deja Vu Sans and/or Symbola fonts.
+
+If you want to pipe the output to a pager, **less -MR** is
+recommended. It will display the inverse characters correctly.
+
+It's even possible to edit the converted text and turn it back into
+ATASCII, if you're very careful. See the **-r** option, below.
+
+Inverse video (characters codes above **$80**) are translated using
+the ANSI/VT-100 reverse video escape sequences. Exception: **$9B**
+(Atari EOL) is translated to **\\n** (newline).
+
+OPTIONS
+=======
+
+-i
+  Input uses Atari XL/XE International Character Set encoding, rather than
+  ATASCII graphics.
+
+-u
+  Use "underlining" for inverse video. Each inverse character is followed by
+  a backspace, then a *_* character. When viewed in a pager such as **less**\(1),
+  this causes the characters to appear underlined. Output created with this
+  option cannot be converted back to ATASCII with the **-r** option.
+
+-t
+  Text mode. Normally, everything but EOL (**$9B**) is converted to a
+  Unicode graphics character. In text mode, ATASCII tabs, backspace,
+  and bells are translated to the ASCII versions.
+
+-r
+  Reverse conversion: Input is plain text, or UTF-8 created by a previous
+  run of **a8cat**; output is ATASCII (or XL ICS, with **-i**). ASCII
+  tabs, backspaces, and newlines will be coverted to the ATASCII
+  equivalent. ASCII carriage returns will be silently ignored.
+
+  Only the UTF-8 codepoints that correspond to ATASCII characters will
+  be converted. If the **-i** option was used to create the input, it
+  must be used with **-r** also.
+
+  **a8cat** will refuse to print ATASCII to a terminal. You must
+  redirect or pipe the output.
+
+-m
+  Magazine listing mode. Rather than Unicode graphics characters,
+  ATASCII characters are printed in symbolic form, e.g. *{clear}* or
+  *{ctrl-A}*. The result is similar to type-in listings in magazines
+  like Antic, Analog, or Compute! Output created with this option
+  cannot be converted back to ATASCII with the **-r** option.
+
+-s
+  Strip the inverse video bit (bit 7) from all characters except the
+  EOL (**$9B**). Output created with this option can be converted
+  back to ATASCII with the **-r** option, but of course there won't
+  be any inverse-video characters in the result.
+
+-v
+  Verbose operation.
+
+**--**
+  End of options; the rest of the arguments are filenames. Use this if you're
+  trying to work with files whose names begin with *-*.
+
+**-h**, **--help**
+  Show built-in help and exit.
+
+**--version**
+  Show version number and exit.
