-	---help---
-	  A pseudo terminal (PTY) is a software device consisting of two
-	  halves: a master and a slave. The slave device behaves identical to
-	  a physical terminal; the master device is used by a process to
-	  read data from and write data to the slave, thereby emulating a
-	  terminal. Typical programs for the master side are telnet servers
-	  and xterms.
-
-	  Linux has traditionally used the BSD-like names /dev/ptyxx for
-	  masters and /dev/ttyxx for slaves of pseudo terminals. This scheme
-	  has a number of problems. The GNU C library glibc 2.1 and later,
-	  however, supports the Unix98 naming standard: in order to acquire a
-	  pseudo terminal, a process opens /dev/ptmx; the number of the pseudo
-	  terminal is then made available to the process and the pseudo
-	  terminal slave can be accessed as /dev/pts/<number>. What was
-	  traditionally /dev/ttyp2 will then be /dev/pts/2, for example.
-
-	  The entries in /dev/pts/ are created on the fly by a virtual
-	  file system; therefore, if you say Y here you should say Y to
-	  "/dev/pts file system for Unix98 PTYs" as well.
-
-	  If you want to say Y here, you need to have the C library glibc 2.1
-	  or later (equal to libc-6.1, check with "ls -l /lib/libc.so.*").
-	  Read the instructions in <file:Documentation/Changes> pertaining to
-	  pseudo terminals. It's safe to say N.

-	  The maximum number of Unix98 PTYs that can be used at any one time.
-	  The default is 256, and should be enough for desktop systems. Server
-	  machines which support incoming telnet/rlogin/ssh connections and/or
-	  serve several X terminals may want to increase this: every incoming
-	  connection and every xterm uses up one PTY.
-
-	  When not in use, each additional set of 256 PTYs occupy
-	  approximately 8 KB of kernel memory on 32-bit architectures.
