The "include" pragma is used to insert the contents of an external BLUE-PHRASE file into the manuscript.
The syntax for the include pragma consists of:
An exclamation point !
The keyword include
A sourceref containing the name of the external manuscript to include.
The target may be an absolute path specifying the target from the file system's root, or a relative path, specifying the target using dot notation (.\filename.blue) or dot-dot notation (..\other-dir\filename.blue).
Here is what an include pragma looks like within the body of a manuscript.
