## So it generates one executable and one shared library
## 1> pam_typtop.so : a pam module that to engage typtop via PAM
## 2> typtop : a binary that manages the typtop database, and called by pam_typtop.so
##             this one also runs with elevated privileges SETGID bit  similar to unix_chkpwd
