FM is a rails app that allows gliding clubs or companies running glider sites to manage flight data.
Currently it is in alpha state. There is some work to be done on the accounting part, which is planned to export accounting information in a Lexware compatible format (i.e. CSV). A website containing further information is planned to be setup soon.
When a first version is officially released, a proper license will be added. It will probably be something like (L)GPL.
