* Packhex is a hex-file compaction utility. It attempts to concatenate
|
| 5 |
|
|
* hex records to produce more size-efficient packaging.
|
| 6 |
|
|
*
|
| 7 |
|
|
* Limitations: Input files must be correctly formatted. This utility
|
| 8 |
|
|
* is not robust enough to detect hex-record formatting
|
| 9 |
|
|
* errors.
