   When you decide to use this package, you automatically agree for the
following conditions:

1. I hold copyrights for these sources, and my name must be left intact, even
   if only part of source file is used.
2. The sources can be used to create any new software which if redistributed
   will be redistributed FREE only (as IRIT executable). You dont have to
   release your sources, but if you do, they must be free as well.
3. No part of the sources, will be used for commercial purposes.
4. All the sources here can be redistributed FREE only, and exactly as they
   are provided to you - the exact same files. You may alter the archive
   program if you prefer (i.e. to zoo format for example), but thats it!
5. Although stated in 4, you may charge for the distribution reasonable amount
   of money (not more that $10).

  I decided to release these sources, mainly for educational purposes. Many
peoples point out, they can learn from the sources, so here is your chance.
  I certainly would like to see this set of programs continue to expand
in two main direction:
1. Improving and/or fixing problems/bugs.
2. Porting these set of program to different environments.

The following is the file: coding.std


These are the coding standards I am using. If you make some changes to the
code, please attempt to follow these rules.

------------------------------------------------------------------------------


GENERAL
-------

	Code should not exceed column 80. If the code is going to "look"
    better with more that 80 columns it is allowed but should be restricted
    as possible.

NESTING
-------
	Nesting of all expressions is by 4 spaces. Tabs used are 8 spaces.

COMMENTS
--------

	Function comments will have the following form:

SPACES
------
	No spaces are allowed after '(' and before ')' in a function call
    or math expression. However, spaces are allowed between arguments after
    the comma or between operations:

	sin(x);
	function1(x, y, z);
	x + 5 * sin(y);

/*****************************************************************************
* Comment body.								     *
*****************************************************************************/

	Internal comments will be aligned to the right to column 80 if the
    are commenting expression in the same line:

	i %= 2;						       /* Is i even? */

	Comments that explains the following block, will be left aligned as
    the block. The comment does not need to be right aligned to column 80 as
    well:

	/* This is a comment for the next line. */
	i %= 2;

BLOCKS
------
	Blocks starts with '{' and ends with '}'. If the block is beginning
    of procedure then it will start with '{' at column 1 and end at column
    1 with '}'. Otherwise it will start with some expression as for/if/while
    etc. in the nesting form:
    expression {
	.
	.
	.
    }

FOR
---
	for (x = 0; x < 10; x++)

    or
	for (x = 0, i = 1;
	     x < 5;
	     x++, i--)

	The body of the for loop can never be in the same line where the ')'
    is. The ')' will be followed by '{' and the body will start in the next
    line nested 4 space deapper:

	for (....)
	    x = sin(j);
    or
	for (....) {
	    x = y / j;
	    y = j + 2;
	}

WHILE
-----
	while (x > 0)
	    x--;					/* Use x = 0 stupid! */
    or
	while (x > 0 && y > 0) {
	    x -= 4;
	    y -= 4;
	}
    or
	while (x > 0 &&
	       x < 5)
	    x /= 2;


IF
--

	if (x > 0)
	    x = -x;
    or
	if (x > 0 && y > 0) {
	    x = -x;
	    y = -y;
	}
    or
	if (x > 0)
	    x = -x;
	else
	    x /= 2;
    or
	if (x > 0)
	    x = -x;
	else if (x < -100)
	    x /= 20;
	else
	    x /= 2;


	Note that if the if expression has else part both bodies will be
    aligned 4 space deep (The body of the if part can not be in same line
    as the if and must be aligned with the else body).


SWITCH
------

	switch (i) {
	    case 1:
		printf("1");
		break;
	    case 2:
		printf("2");
		break;
	    case 3:
		printf("3");
		break;
	    default:
		printf("Too big");
		break;
	}
