license

Was just going through the documention of heimdal, have one doubt.. as mentioned in http://www.stacken.kth.se/lists/heimdal-discuss/2003-03/msg00022.html is heimdal free of all export license restrictions. Or are there any specific restrictions, like on some countries, etc..? this question because I happened to see some US copyright restriction as below :

Export of this software from the United States of America may
require a specific license from the United States Government.
It is the responsibility of any person or organization contemplating
export to obtain such a license before exporting.
