     Name
          intro - Introduces text processing commands.

     Description
          This section describes use of the individual commands
          available in the XENIX Text Processing System.  Each
          individual command is labeled with the letters CT to
          distinguish it from commands available in the XENIX
          Operating and Development Systems.  These letters are used
          for easy reference from other documentation.  For example,
          the reference mm(CT) indicates a reference to a discussion
          of the mm command in this section, where the letter ``C''
          stands for ``command'' and the letter ``T'' stands for
          ``Text Processing''.

     Syntax
          Unless otherwise noted, commands described in this section
          accept options and other arguments according to the
          following syntax:

                       name [option...] [cmdarg...]

          This syntax is detailed below:

          name         The filename or pathname of an executable file

          option       A single letter representing a command option.
                       By convention, most options are preceded with a
                       dash.  Option letters can sometimes be grouped
                       together as in -abcd or they are specified
                       individually as in -a -b -c -d . The method of
                       specifying options depends on the syntax of the
                       individual command.  In the latter method of
                       specifying options, arguments can be given to
                       the options. For example, the -f option for
                       many commands often takes a following filename
                       argument.

          cmdarg       A pathname or other command argument not
                       beginning with a dash or a period (.).  It may
                       also be a dash by itself indicating the
                       standard input.

     Diagnostics
          Upon termination, each command returns 2 bytes of status,
          one supplied by the system and giving the cause for
          termination, and (in the case of ``normal'' termination) one
          supplied by the program.  (See wait(S) and exit(S).) The
          former byte is 0 for normal termination; the latter is
          customarily 0 for successful execution and nonzero to
          indicate troubles such as erroneous parameters, bad or
          inaccessible data, or other inability to cope with the task
          at hand.  It is called variously ``exit code,'' ``exit
          status,'' or ``return code,'' and is described only where
          special conventions are involved.

     Notes
          Many commands do not adhere to the given syntax.
