Reviews

Open Source Licensing

Very Good ******** (8 out of 10)

A very clearly written legal text written by a lawyer! Astounding!

Nevertheless, he manages to cover his subject very well and in detail (even if he only goes through the most popular licensees and some that he has written himself). He also manages to explain some of the problems with rank amateurs (aka developers and programmers) that tries to play lawyers and messes things up in extremis.

Clearly recommended reading if you're into OSS, even if the subject sometimes gets a bit dry.
