+openssh-krb5 (Secure Shell daemon and clients - with Kerberos)
+
+ssh (Secure Shell) is a program for logging into a remote machine and
+for executing commands on a remote machine.  It is intended to replace
+rlogin and rsh, and provide secure encrypted communications between
+two untrusted hosts over an insecure network.
+
+This package builds openssh with Kerberos support, and it does not 
+conflict with the stock Slackware package (in fact, that package needs
+to stay, as this depends on other files contained in it).
+
+You will need to start /etc/rc.d/rc.sshd.krb5 during boot.
+
+This requires krb5.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|' on
+# the right side marks the last column you can put a character in.  You must make
+# exactly 11 lines for the formatting to be correct.  It's also customary to
+# leave one space after the ':'.
