</div></div>This is great, that you got this far! Can you write up a wiki page in<br>
the dev section. Don't worry too much about formatting, mostly just get<br>

As for Makefiles, if you use the the Library Template, then the Makefile<br>
will work on MinGW, Cygwin, Mac OS X, GNU/Linux, Android, iOS, etc.<br>
