GMW 2013 perspectives on mobile learning

Last week I had the opportunity to present our project results at the GMW 2013 conference in Frankfurt a.M. and at the "Fernausbildungskongress" of the German Bundeswehr. The GMW conference is one of the prominent meetings of the German-speaking media-education and e-learning community for discussing the latest developments in education and learning with technologies.

print "\n"; # note the double quotes!

or modern Perl (works practically everywhere but very very old servers).

use v5.10; # you always want to put this line to the beginning of your file!
