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.
