tablor – Create tables of signs and of variations

The pack­age al­lows the user to use the com­puter al­ge­bra sys­tem XCAS to gen­er­ate ta­bles of signs and of vari­a­tions (the ac­tual plot­ting of the ta­bles uses the METAPOST macro pack­age tableauVari­a­tions). Tables with for­bid­den re­gions may be de­vel­oped us­ing the pack­age.
A con­fig­u­ra­tion file per­mits some con­fig­u­ra­tion of the lan­guage to be used in the di­a­grams.
The tablor pack­age re­quires that shell es­cape be en­abled.
