colordoc – Coloured syntax highlights in documentation

The pack­age is used in doc­u­men­ta­tion files (that use the doc pack­age); with it the code list­ings will high­light (for ex­am­ple) pairs of curly braces with match­ing col­ors.
Other de­lim­iters like \if ... \fi, are high­lighted, as are the names of new com­mands.
All this makes code a lit­tle more read­able, and helps dur­ing pro­cess of writ­ing.
Three op­tions are pro­vided, in­clud­ing a non-color op­tion de­signed for print­ing (which num­bers de­lim­iters and un­der­lines new com­mands).
