It doesn't print pretty. There are a lot of things it doesn't handle directly, primarily Specializations on Language and Knowledge Skills and use of capacity for adding cyberware other than limbs/skull/torso. You also are not prevented from or warned about some illegal character build, mainly cyber/bio interaction.
But overall it works ok and should allow for some assistance is chargen until a proper SR4 chargen is built.
P.S. My name is part of the file, but that isn't by my choice. The original author is Autarkis and some of the data comes from the NSRCG, particularly Knowledge and Language Skill lists. I'm just the last person to make changes, so it was posted with the qualifier of my name by the person hosting it, Shadow.
