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
       properties 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.
