 Will skip building extensions which are marked with an '!' char.
 Mostly because they still not ported to specified platform.
 
+If any extensions are listed with a '+' char then only those
+extensions will be built, but only if they arent countermanded
+by an '!ext' and are appropriate to the type of building being done.

 If '--static' specified, only static extensions will be built.
 If '--dynamic' specified, only dynamic extensions will be built.
