+.SYNOPSIS
+    Haxe PipeScript Transpiler.
+.DESCRIPTION
+    Transpiles Haxe with Inline PipeScript into Haxe.
+
+    Multiline comments with /*{}*/ will be treated as blocks of PipeScript.
+
+    Multiline comments can be preceeded or followed by 'empty' syntax, which will be ignored.
+
+    This for Inline PipeScript to be used with operators, and still be valid Haxe syntax. 
+
+    The Haxe Inline Transpiler will consider the following syntax to be empty:
+
+    * ```null```
+    * ```""```
+    * ```''```
