- 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:
-
- /*****************************************************************************
- * 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.
-
- 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 be in the same line where the ')' is
- if it has only one expression. Otherwise 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;
- }
