Syntax:
#INCLUDE instructs the compiler to read the contents of filename before continuing to process options in the current file.
This can be useful if you want to have a particular configuration file for a project (or, under linux, in your home directory), but still want to have the global options that are set in a global configuration file.
Example:
This will include /etc/fpc.cfg if you’re on a linux machine, and will include c:\pp\bin\fpc.cfg on a dos machine.
