I first started thinking about this program while working on my master thesis.
I'm doing computational chemistry research and have to work frequently with xyz coordinate files. Many times it came to my mind that things would be much simpler if a certain atom could lie in a certain position compared to the principle axes. Doing this requires some simple, but time consuming, mathematics. Ideally this could be done by my computer. Due to a lack of time during my master thesis I did'nt start programming yet.
Nowadays I'm still working with computational chemistry and I decided it would be time to write my little program. And here we are, a first version has been released. It's still very basical, but does everything I need it to do and it's already much more user friendly than some other program I have been using for this purpose :-) But there are always improvements to be made (see future goals).
