+.Sh DESCRIPTION
+The
+.Nm
+file contains a list of valid shells available on the system.
+A shell is a command line interpreter that reads user input and executes
+commands.
+For each shell a single line should be present, consisting of the
+shell's path, relative to root.
+.Pp
+A hash mark
+.Pq Sq #
+indicates the beginning of a comment; subsequent
+characters up to the end of the line are not interpreted by the
+routines which search the file.
+Blank lines are also ignored.
+.Pp
+The
+.Xr chpass 1
+program will not let regular users change their default shell to one not
+listed in the
+.Nm
+file.
+The
+.Xr ftpd 8
+daemon denies access to users who are not using one of the listed shells.
