1. Preview
----------

   This utility allows you to define your own conversion tables for Columns
and Convert (a small text conversion utility, which will be described later).

   Main features:

     - Written completely in assembly

     - Kickstart 2.0 and 3.0 compatible

     - Kickstart 2.0 look

2. System requirements
----------------------

   This program requires:

      - Kickstart 1.2 or higher

      - Arp.library

      - Req.library

      - Some free memory


3. How to start CTED
--------------------

   There are two ways to start Columns and pass it the parameters:

      - Start it from CLI

      - Start it from Workbench by doubleclicking its icon.


4. The main window
------------------

   If you start CTED, the main window will appear.

   This window contains:

      - A part of the conversion table with proportional gadget used for
        scrolling.  This table has format "x (X) -> y (Y)", where X is the
        character to be converted (x is its code) and Y is the character,
        which will X be converted to (y is its code). One line of the table is
        highlighted (displayed in inverse video). This is the active line,
        which is being edited.

      - Two string gadgets named "Code" and "ASCII" used for editing the table
        manually.

      - The LOAD gadget - loads a conversion table from specified file

      - The SAVE gadget - saves the conversion table to specified file

      - The INIT gadget - performs conversion table initialization

      - The DIFF gadget - performs differential scanning. You supply two files
        (each maximally 256 bytes long). CTED will create a conversion table
        saying each character in the first file will be converted to the
        character found in the second file on the same position.

      - The SCAN gadget - performs "learning" scanning. You supply the file
        you wish to convert and CTED will search for non-recognised characters
        (characters, which are marked "without conversion" - (x -> x) and
        aren't in range 32..126). File parts containing this characters will
        be displayed with this character in boldface and other non-recognised
        characters in italics. Then a colon will be displayed as a prompt and
        you will have to enter one character. If you won't enter anything,
        this line will be ignored and scanning will be continued. If you enter
        ESCAPE, the scanning process will be aborted. If you enter a
        character, this character will be written into the conversion table as
        a conversion for that unknown character.


5. The Convert utility
----------------------

   Convert  is  a  small  command-line  utility (can be called only from CLI),
which performs a text file conversion.  This utility requires the arp.library.

   Arguments:

      TABLE - specifies the conversion table you wish to use

       FROM - specifies the source file

         TO - specifies the destination file. If you omit this name, the
              output will be written back to the source file.

        BUF - (not needed) - specifies I/O buffer size (default is 32768)
              If you process longer files, larger values of this parameter
              can increase speed of the operation.

   Characters converted to 0x00 will be removed from the output file.


6. The conversion table format
------------------------------

   The conversion table file contains one byte for each possible character
code (its size is 256 bytes). This byte contains the character which the
original character will be converted to.
