GlobalSight is free and open source.
You can download the source code for official releases from the GlobalSight page on sourceforge.net.
You can also download the latest source code from our CVS repository. The code is read-only and unofficial.
Set your CVSROOT to pserver:firstname.lastname@example.org:/CVSServer and then check out normally:
cvs -z3 checkout GlobalSightSource
The source tree is large so we can recommend enabling compression.
