+	IFPIGGY command tests whether current loaded APK file (character animation) is "piggy.apk".
+	If it is, execution continues to the next line.
+	Otherwise execution continues after first "#ELSE" or "=ELSE".
+
+	Please note that this does not work like you are used to from saner languages.
+	IFPIGGY does not have any blocks. It only searches for first #ELSE, so you can have stuff like:
+		IFPIGGY
+		IFITEM someitem
+		#ELSE
+		...
+	This is effectively logical AND.
