+      The tcb package contains core components of our tcb suite implementing the alternative
+      password shadowing scheme on Openwall GNU Linux (Owl). It is being made available
+      separately from Owl primarily for use by other distributions.
+
+      The package consists of three components: pam_tcb, libnss_tcb, and libtcb.
+
+      pam_tcb is a PAM module which supersedes pam_unix. It also implements the tcb password
+      shadowing scheme. The tcb scheme allows many core system utilities (passwd(1) being
+      the primary example) to operate with little privilege. libnss_tcb is the accompanying
+      NSS module. libtcb contains code shared by the PAM and NSS modules and is also used
+      by user management tools on Owl due to our shadow suite patches.
