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.

URLCODING(3)						 libbash urlcoding Library Manual					      URLCODING(3)

NAME

     urlcoding -- a Libbash library for encoding and decoding URL's.

SYNOPSIS

     urlEncodeString [-l] <STRING>
     urlEncodeFile [-l] <FILE>
     urlEncodeStream [-l]
     urlDecodeString <STRING>
     urlDecodeFile <FILENAME>
     urlDecodeStream

DESCRIPTION

     urlcoding is a collection of functions that convert ASCII-text to standard URL's and vice-versa. The AWK code used is based on code by Heiner
     Steven <heiner.steven@odn.de>

     The function list:
	   urlEncodeString  Creates a URL from an ASCII string
	   urlEncodeFile    Converts a file into URL-valid text
	   urlEncodeStream  Converts standard input into URL-valid text
	   urlDecodeString  Converts a URL-encoded text back to a plain-text form
	   urlDecodeFile    Coverts URL-encoded text in a file back to plain text
	   urlDecodeStream  Converts URL-encoded standard input to text

     Detailed interface description follows.

     The [-l] option for the encoding functions should be used when line-feed characters ('
') are to be encoded as well.

     All functions print the results of their conversions to standard output.

     The exit status of all functions is that of the command 'awk', with '0' for success

FUNCTIONS DESCRIPTIONS

   urlEncodeString [-l] <STRING>
     Converts STRING - a string of ASCII characters - to URL.

   urlEncodeFile [-l] <FILE>
     Coverts FILE of URL-encoded text to plain text

   urlEncodeStream [-l]
     Converts text from standard input to URL-text.

   urlDecodeString <STRING>
     Converts URL-encoded string STRING back to text.

   urlDecodeFile <FILENAME>
     Converts the URL-encoded text in FILE to plain text.

   urlDecodeStream
     Converts the URL-encoded text from standard input to plain-text
