Added --define to lwasm documentation.
Added documentation of the -D/--define command line option for lwasm. It has
been present for a long time but has somehow escaped documentation.

80 >LWASM accepts plain text files in a relatively free form. It can handle | |
81 lines terminated with CR, LF, CRLF, or LFCR which means it should be able | |
82 to assemble files on any platform on which it compiles.</P | |
83 ><P | |
84 >Each line may start with a symbol. If a symbol is present, there must not | |
85 be any whitespace preceding it. It is legal for a line to contain nothing | |
86 but a symbol.</P | |
87 ><P | |
88 >The op code is separated from the symbol by whitespace. If there is | |
89 no symbol, there must be at least one white space character preceding it. | |
90 If applicable, the operand follows separated by whitespace. Following the | |
91 opcode and operand is an optional comment.</P | |
92 ><P | |
93 > It is important to note that operands cannot contain any whitespace | |
94 except in the case of delimited strings. This is because the first | |
95 whitespace character will be interpreted as the separator between the | |
96 operand column and the comment. This behaviour is required for approximate | |
97 source compatibility with other 6x09 assemblers. </P | |
98 ><P | |
99 >A comment can also be introduced with a * or a ;. The comment character is | |
100 optional for end of statement comments. However, if a symbol is the only | |
101 thing present on the line other than the comment, the comment character is | |
102 mandatory to prevent the assembler from interpreting the comment as an opcode.</P | |
103 ><P | |
104 >For compatibility with the output generated by some C preprocessors, LWASM | |
105 will also ignore lines that begin with a #. This should not be used as a general | |
106 comment character, however.</P | |
107 ><P | |
108 >The opcode is not treated case sensitively. Neither are register names in | |
109 the operand fields. Symbols, however, are case sensitive.</P | |
110 ><P | |
111 > As of version 2.6, LWASM supports files with line numbers. If line | |
112 numbers are present, the line must start with a digit. The line number | |
113 itself must consist only of digits. The line number must then be followed | |
114 by either the end of the line or exactly one white space character. After | |
115 that white space character, the lines are interpreted exactly as above. </P | |
