The standard RETRO system is built using the Nga VM[1] and an
|
||
|
|
image file. The Python implementation consists of several files,
|
||
|
|
but it's nice to have a single file copy for easier deployment.
|
||
|
|
This tool combines the pieces into a single source file.
|
||
|
|
|
||
|
|
Output will be written to stdout.
|
||
|
|
|
||
|
|
## Code
|
||
|
|
|
||
|
|
Extract and generate the single file source.
