[Gambas-user] C like #include for Gambas

[Randall Morgan]

I don't know about Gambas but Python has many libraries for this. Just
google it. If you insist on pre-processing, a simple python script could
get it done quickly. I'm a firm believer in using the tool that makes the
most sense for the project. Of course, that depends on the person and
project....

If you ask me if it can be done. The answer is YES, it can always be done.
The correct questions however are... What will it cost, and how long will
it take?
