Description: Perl is not the only language i'm learning right now, i'm also learning english ;)... i was looking for a little tool, which would stay on the top of my desktop and show english words with a translation changing them in every N seconds. i'm using FlashKard, coming with KDE, and i have alredy collected a little vocabulary. so i decided to make a script which would use a file created by FlashKard (xml) and show words randomly.
don't judge it too strictly, it's my first public code.
i would be happy to get any notices, corrections or additions.
#!/usr/bin/perl
