Conversion from VERILOG READMEMB to INTEL HEX

The following script was written for a project, which needed to initialize some memories. The data was given in VERILOG's READMEMB (XILINX) and was needed to be in INTEL HEX format (ALTERA).
The script is far from being complete i.e. support any input file.
The script can be used as a very good starting point to write your own parser.

1. Here is an example of what the code does:

input file (readmemb)
000000000000
000000100111
000000100110
100110100111
output is intel hex
1 Start code 1 An ASCII colon, ":".
2 Byte count 2 The count of the character pairs in the data field.
3 Address 4 The 2-byte address at which the data field is to be loaded into memory.
4 Type 2 00, 01, or 02.
5 Data 0-2n From 0 to n bytes of executable code, or memory loadable data. n is normally 20 hex (32 decimal) or less.
6 Checksum 2 The least significant byte of the two's complement sum of the values represented by all the pairs of characters in the record except the start code and checksum.
:020000000000fe
:020001000027d6
:020002000026d6
:0200030009a74b
:020004000025d5
