/* the IEM16 external is a runtime-library for miller s. puckette's realtime-computermusic-software "pure data"
* therefore you NEED "pure data" to make any use of the IEM16 external
* (except if you want to use the code for other things)
* download "pure data" at
http://pd.iem.at
ftp://iem.at/pd
*
* if you are looking for the latest release of the IEM16-external you should have another look at
ftp://iem.at/pd/Externals/IEM16
*
* IEM16 is published under the GNU GeneralPublicLicense, that must be shipped with IEM16.
* if you are using Debian GNU/linux, the GNU-GPL can be found under /usr/share/common-licenses/GPL
* if you still haven't found a copy of the GNU-GPL, have a look at http://www.gnu.org
*
* "pure data" has it's own license, that comes shipped with "pure data".
*
* there are ABSOLUTELY NO WARRANTIES for anything
