Syntax

$include <Filepath> [api folder optional]
$includeFolder <Path> [api optional]

Syntax	Description
`$include "Path/Filename.rogue"`	Includes `Path/Filename.rogue`.
`$include Path/Filename.rogue`	Can omit quotes if filepath contains only common alphanumeric characters and `~/:\`.
`$include Path/Filename`	Can omit `.rogue`.
`$include LibraryName`	Includes `LibraryName/LibraryName.rogue` or `LibraryName.rogue`, whichever is found first.
`$include Path [folder]`	Recursively includes all `.rogue` files in the specified folder.
`$includeFolder Path`	Alternate syntax for `$include Path [folder]`.
`$include Filepath [optional]`	No error generated if filepath does not exist.
`$include Filepath [api]`	All elements of included file are designated `[api]`, preventing unused classes and methods from being culled during compilation and making them available to introspection.
`$include Filepath [target("ObjC")]`	Only includes the file if the named `--target` was specified during compilation.

Description

Immediately parses the specified source file.
For a given source file, only the first $include has an effect - subsequent includes of the same file are ignored.
The order of includes typically doesn't matter - classes, routines, and most program elements can be referenced before their definitions are $included.
$define and $macro definitions must be $included before they are referenced in source code - for example, by defining them in Definitions.rogue and making $include Definitions be the first $include in a program.
The path of every included file is automatically added to the search path for future includes.
