NAME

       ptywrap - fool programs into thinking they are talking to a pseudo-tty

SYNOPSIS

       ptywrap

DESCRIPTION

       ptywrap is a simple tool to wrap other programs' input/output streams in a pseudo-tty.

       Many  programs  determine whether or not they should buffer their input/output based on whether or not these are connected to a pseudo-tty.
       Ptywrap can be used to fool programs into thinking that they are connected to a	pseudo-tty  even  if  they  are  not  (e.g.  even  if  the
       input/output is redirected to a file).

NAME

       cadabra - field-theory motivated computer algebra system

SYNOPSIS

       cadabra

DESCRIPTION

       Cadabra is a computer algebra system for the manipulation of tensorial expressions.

       The output of cadabra is either plain text or UTF8 encoded Unicode (see the environment variables described below). The line-breaking prop-
       erties of the latter are used to wrap large expressions are reasonable points. In addition to the standard output, cadabra can print status
       information, which is wrapped in special <status>...</status> blocks.

OPTIONS

	--silent
	      Disables all output, except for output generated by the @print algorithm.

	--loginput
	      Copy the input into the log file.

	--input filename
	      Read the indicated file as input before switching to console input.

	--prompt string
	      Set the prompt of the interactive session to the indicated string.

ENVIRONMENT VARIABLES

       The following variables toggle various features on or off, depending on whether the variable is set or not:

	CDB_PRINTSTAR
	      Display a star to indicate products. Without this setting, a space is used.

	CDB_USE_UTF8
	      Use  UTF8  encoding  for	output. This in particular will introduce non-breakable spaces to group objects together, as well as zero-
	      width non-breakable spaces to prevent line-breaks after brackets, underscore and caret symbols.  When this variable is not set,  the
	      output will be plain ASCII without any special symbols.

SEE ALSO
