Bug in sample application

[Alexandre Sagala <asagala@eclipsys.qc.ca>]

I found a minor bug in the sample application supplied in the PAM Developer 
Manual 

http://www.kernel.org/pub/linux/libs/pam/Linux-PAM-html/pam_appl-8.html

    if(argc > 2) {
        fprintf(stderr, "Usage: check_user [username]\n");
        exit(1);
    }

if suppose to be if(argc <2) and not >

 Is this the right place to post this?? If not sorry
