How to get the CVS client user name from the script file of module programs

[Aric Wang]

Hi,

I use the modules file to configure a perl script to run when user checkout some module. From the cvs manual, the only parameter to the program is the module name. How can I get the client user name to check if the user has the permission to checkout the module? Or does anyone have any other method to do this?

Thanks and regards,
